POOL COUNSELOR
With the first warm rays of sunshine, the anticipation of the pool season increases. But before you get into the refreshing water, your pool should be thoroughly woken up from hibernation. A structured spring check is not only sensible, but essential to ensure the hygiene, safety and longevity of the pool system. Below you will find detailed instructions on how to optimally prepare your pool for the season – including product recommendations from chlorladen.ch, your expert for water care and accessories.
1.1 Visual inspection and cleaning
Before water is added or treated, it is advisable to carry out a thorough visual inspection of the entire pool. Are there any visible cracks, discoloration or deposits? Then now is the ideal time to remove them. Use a special pool brush and a dirt and leaf net to effortlessly remove leaves, algae residue and coarse dirt. For stubborn deposits on the walls, a pool edge cleaner is suitable, which even adheres to vertical surfaces and works efficiently.
1.2 Technical check: filter, pump & co.
After winter storage, it is crucial to put all the technology into operation and check that it is working properly. The filter system, circulation pump and, if necessary, heat pump should be checked for leaks, blocked pipes or wearing parts. If replacement is necessary, it is worth taking a look at the chlorladen.ch range of spare parts and filter materials.
1.3 Filling or refreshing water
Depending on the wintering method, fresh water is filled in or the existing water level is topped up. Make sure that the water level reaches approximately halfway up the skimmer. Now is the right time for a comprehensive water analysis using test strips or digital measuring devices.
1.4 Setting the water values
If the measured values are not within the ideal range (pH value: 7.0-7.4; free chlorine: 0.5-1.0 mg/l), a correction is necessary. If the pH values are too high, pH-Minus is recommended, while pH-Plus is used for low values. You can find various versions of these products at chlorladen.ch. Ensure slow dosing and good circulation.
1.5 Carry out shock chlorination
Shock disinfection is particularly useful at the start of the season to eliminate possible germs and algae residues. Use a highly effective product such as Active 65 chlorine granulate, adding it directly to the water or via a skimmer while the circulation is running. Important: After shock chlorination, do not enter the pool for several hours and check the water values.
1.6 Don’t forget algae prophylaxis
The addition of an algaecide is recommended to prevent the formation of algae. A product such as Algizid Ultra works reliably against green, black and vertically growing algae and is particularly gentle on the material.
1.7 Checking and adding accessories
Also check your pool cover, skimmer, ladders, hoses and dosing floats for wear and tear or damage. If you don’t yet have a pool vacuum cleaner or pool robot, you should invest now at the latest – the selection ranges from manually operated vacuum cleaners to automated cleaning systems.
After a long winter break, your pool needs special attention before you can use it again. Thorough cleaning is essential to remove dirt, deposits and possible impurities. This article shows you step by step how to get your pool back in shape after the winter – including recommendations for suitable products from chlorladen.ch.
2.1 Removing and cleaning the cover
If you have protected your pool with a winter cover, remove it carefully. Make sure that no collected rainwater or dirt gets into the pool. Clean the cover thoroughly with a hose or pressure washer before drying and storing it.
2.2 Removing coarse soiling
Leaves, branches and insect remains have collected in the pool over the winter. Remove these with a landing net or skimmer net. For fine dirt and sand residue on the floor, we recommend a vacuum cleaner or pool vacuum cleaner, which you can easily find at chlorladen.ch.
2.3 Check the water level and drain if necessary
If the pool has been overwintered with water, you should check whether the water needs to be drained or partially replaced. Heavily soiled or greenish water should be completely replaced. Use a submersible pump or the drain connection of your pool for this.
2.4 Cleaning the pool walls and floor
Algae and limescale deposits tend to build up during the cold season. These deposits can be efficiently removed with a pool brush and a suitable pool cleaner such as the edge cleaner or a pool cleaner concentrate. Stubborn areas can be treated with a sponge or pad.
2.5 Cleaning the filter system or replacing the medium
Before you fill in new water or treat old water, you should clean the filter system thoroughly. Depending on the system, this means backwashing sand filters or washing out or replacing cartridges or filter balls. If you are using filter balls, check whether they need to be replaced – e.g. with 700g filter balls from chlorladen.ch.
2.6 Filling with water
Once the pool is clean, you can fill it with fresh water. Make sure the water pressure is stable and avoid splashing water, which can leave limescale on the edges of the pool. The water level should reach about halfway up the skimmer.
2.7 Water analysis and initial treatment
Carry out an initial water analysis – pH value, free chlorine and alkalinity are crucial. Use test strips or digital measuring devices for this. For initial treatment, we recommend shock chlorination with chlorine granulate Active 65. The water should then be circulated for a few hours.
2.8 Activate control round & technology
Before you put the technology into permanent operation, check all seals, connections and hoses. Then activate the pump and check that the water circuit is working properly. Slight air bubbles in the first few minutes are normal.
Conclusion
Professional spring cleaning lays the foundation for a hygienic, safe and relaxing pool season. With the right accessories and suitable cleaning products from chlorladen.ch, you can get started effortlessly. Pay attention to regular checks and clean technology – then nothing will stand in the way of swimming fun!

A well-maintained pool starts with clean water quality – which in turn starts with a precise analysis. Especially at the start of the season, water analysis is an essential step in creating optimal swimming conditions, avoiding health risks and minimizing follow-up costs due to incorrect dosing. This article shows you why water analysis is so important, how to carry it out correctly and which measuring methods have proven their worth – including product tips from chlorladen.ch.
3.1 Why is water analysis so important?
Without a sound analysis of the water values, any form of pool maintenance is a gamble. A pH value that is too high reduces the effectiveness of disinfectants such as chlorine, while a pH value that is too low can corrode materials and cause skin and eye irritation. An incorrect alkalinity value also significantly affects the stability of the water parameters. Furthermore, an imbalanced water balance can lead to algae formation, limescale deposits or corroding pipes.
3.2 Overview of the most important water values
The basic parameters of a water analysis include
- pH value: Optimally between 7.0 and 7.4
- free chlorine: Between 0.5 and 1.0 mg/l
- Total alkalinity (TA): 80-120 mg/l
- Cyanuric acid (stabilizer): Maximum 50 mg/l for chlorine-containing care
- Calcium hardness: 150-400 mg/l (depending on region and pool type)
These values form the basis for a stable water balance and prevent problems with turbidity, algae or unpleasant odors.
3.3 Comparison of measurement methods
There are different methods for determining the water values:
– Test strips: Cheap and fast, but limited accuracy. Ideal for an initial assessment.
– Tablet tester (DPD/Phenol Red): Good compromise between accuracy and price.
– Digital pool tester: Highest accuracy, some with app connection and data history.
Test strips are sufficient for daily checks, but a more precise method should be used for weekly checks or after the use of chemicals.
3.4 Step-by-step instructions for water analysis
- Take a water sample from a depth of around 30 cm, not directly at the inlet nozzles.
2. Use the selected test method (strips, tablets or digital).
3. Compare the values with the ideal ranges.
4. Document the results to identify fluctuations over the course of the week.
5. Adjust the water treatment accordingly (e.g. regulate pH, adjust chlorine value).
3.5 The right products at hand
For a reliable analysis, we recommend the PoolLab 2.0 photometer, which can measure up to 24 parameters – ideal for ambitious pool owners or operators. Alternatively, chlorladen.ch also offers classic test strips for pH and chlorine for quick use.
Conclusion
Regular water analysis is not a luxury, but the basis for clean, safe and stable pool water. Only those who know their values can take targeted action – and save not only nerves but also money. chlorladen.ch provides you with everything you need for this: from inexpensive test strips to digital premium testers.
Spring is here, temperatures are rising – high time to get the pool going. But before you jump into the water for the first time, you should make sure that your pool is equipped with the right care products. There is a wide range of pool chemicals to choose from, but some products are particularly important at the start of the season. In this article, we show you which chemicals you should definitely have on hand and how they work – with specific product recommendations from chlorladen.ch.
4.1 Why pool chemicals are indispensable
Without the right chemical water care, even a clear-looking pool can become a breeding ground for bacteria, algae and fungi. Pool chemicals not only ensure germ-free water, but also help to keep the water values stable, prevent material damage and reduce the load on the filter technology.
4.2 The basis: Disinfection with chlorine
Chlorine is the classic pool chemical – and for good reason. It reliably kills germs, is effective against organic soiling and ensures hygienically clean water. To get started, we recommend shock chlorination with a fast-dissolving product such as chlorine granulate Aktiv 65, which is particularly effective and dissolves without leaving any residue.
4.3 Regulating the pH value: The prerequisite for effect
The pH value influences the effect of almost all other pool chemicals – especially chlorine. A pH value that is too high (>7.6) reduces the disinfection effect, while one that is too low (<6.8) can irritate metal parts and skin. The value can be lowered quickly and precisely with pH-Minus liquid 25 kg, while pH-Plus is used to raise the value. Ideally, digital test devices or test strips should be used for checking.
4.4 Algae under control: prevention instead of treatment
Algae can form quickly, especially in warmer temperatures. To prevent this, the use of algaecides is recommended. These prevent the growth of green, black and yellow algae in advance. Important: Algaecides have a preventative effect – in the event of an acute algae infestation, shock chlorination is necessary first.
4.5 Flocculants and hardness stabilizers
The finest suspended particles that are not removed by the filter can be bound with flocculants. These ensure crystal clear water. In regions with hard water, hardness stabilizers help to prevent limescale deposits. Both products are useful, but not always necessary – a water analysis will show the need.
Conclusion
A well-equipped pool chemicals cabinet is half the battle for a successful start to the season. With disinfectants, pH regulators and preventative algaecides, you can lay the foundation for safe, clear and clean water. At chlorladen.ch you will find all the products you need – in tested quality and suitable container sizes.
The pH value is one of the most important parameters in pool care. It not only influences the effectiveness of chlorine, but also the water quality, skin tolerance and the service life of your pool technology. An unstable pH value can cause numerous subsequent problems – from algae growth and cloudy water to corrosion. In this article, you will learn how to measure the pH value, set it correctly and keep it stable in the long term. With product tips from chlorladen.ch, of course.
5.1 What is the pH value and why is it important?
The pH value indicates whether your pool water is acidic or alkaline. The scale ranges from 0 (very acidic) to 14 (very alkaline), whereby a pH value between 7.0 and 7.4 is considered optimal for pool water. Disinfectants such as chlorine work best within this range, skin and eyes are protected and the material is not attacked.
5.2 Causes of fluctuating pH values
Once set, the pH value does not automatically remain stable. The following factors influence it:
- Refill water (usually calcareous)
- Environmental influences (rain, leaves, dust)
- Frequent use by bathers
- Use of chemicals (e.g. chlorine slightly increases the pH value)
Regular checks are therefore particularly important – ideally two to three times a week during the peak season.
5.3 Measuring the pH value
You can measure the pH value with test strips, tablet tests or digital devices. The PoolLab 2.0 photometer is particularly precise, providing you with exact values and even a progress check. However, simple test strips are often sufficient for everyday use.
5.4 Setting the pH value correctly
If your pH value is outside the ideal range, you need to take countermeasures:
– pH too high (>7.4): Use [pH-Minus flüssig](https://www.chlorladen.ch/ph-regulierung/ph-minus-fluessig-25kg/) or granules.
– pH too low (<7.0): Use pH-Plus to raise the pH.
It is important to add the water evenly while the circulation is running. Start with small quantities, measure again after a few hours and adjust as required.
5.5 Keeping the pH value stable in the long term
In addition to regular measurement and readjustment, the following tips will help:
– Remove dirt regularly (e.g. leaves, sand)
– Do not overdose the water with chemicals
– Keep an eye on the TA value (total alkalinity) – ideally 80-120 mg/l
If the TA value is too low, the pH value will also fluctuate significantly more. Appropriate agents for increasing the TA are also available commercially.
Conclusion
The pH value is at the heart of pool water care. Only when it is right can other products such as chlorine or algaecides take full effect. With the right products, a little routine and support from reliable testers, you can keep your pool water perfectly balanced. At chlorladen.ch you will find pH regulators and test systems in tested quality – for stable, clear water from the beginning to the end of the season.

Chlorine is the most commonly used disinfectant in pool care – and for good reason. It is effective, fast-acting and inexpensive. However, chlorine only serves its purpose without causing side effects such as irritation or unpleasant odors if it is dosed and used correctly. In this article, you will find out how chlorine works, how to dose it correctly and what mistakes you should avoid – including product recommendations from chlorladen.ch.
6.1 How does chlorine work in the pool?
Chlorine kills bacteria, viruses and fungi and oxidizes organic impurities in the water. It breaks down into hypochlorous acid and hypochlorite – these compounds perform the actual disinfection. A stable pH value of between 7.0 and 7.4 is required for chlorine to be effective.
6.2 The different forms of chlorine
Several chlorine variants are available for pool maintenance:
– Fast-dissolving chlorine granules: Ideal for shock treatments, e.g. chlorine granules Active 65
– Slow-dissolving chlorine tablets: For continuous disinfection in the dosing float
– Liquid chlorine: Frequently used in the professional sector or with automatic dosing systemsFor private pools, a combination of tablets for everyday use and granules for special applications is usually sufficient.
6.3 When is shock chlorination necessary?
Shock chlorination is a one-off, intensive disinfection. It makes sense:
-
At the start of the season after basic cleaning
-
For extreme use or high temperatures
-
In case of algae infestation or cloudy water
-
After heavy rain or thunderstorms
Double to triple the normal amount of chlorine granulate is added – while the circulation is running.
6.4 Correct dosage and application
The ideal concentration of free chlorine is 0.5 to 1.0 mg/l. An overdose can cause eye irritation and skin problems, too little chlorine leads to insufficient disinfection. Important tips:
– Never sprinkle chlorine directly into foil pools – preferably via skimmers or dissolved in water
– Never mix chlorine products with other chemicals
– Store chlorine in a dry, cool and childproof place
– Use a digital tester such as the PoolLab for precise readings6.5 Stabilizing chlorine – especially in the sun
UV radiation quickly breaks down chlorine in water. A stabilizer such as cyanuric acid slows down this process. Many products, such as Multifunctional Tablets 200g 5in1, already contain an integrated stabilizer and also offer flocculation and algae prevention.
Conclusion
Chlorine is and remains the classic in pool care – simple, efficient and reliable. However, it only provides the desired water quality when used correctly. With high-quality products from chlorladen.ch and a little know-how, your pool will remain hygienically clean and your bathing fun unclouded.

Cloudy water is one of the most common sources of frustration for pool owners. It looks unappetizing, spoils the fun of swimming and is often an indication of hygiene or technical problems. But don’t worry: with the right diagnosis and targeted measures, you can get your water crystal clear again. In this article, we show you the most common causes of cloudy pool water and how you can reliably remedy them – including product recommendations from chlorladen.ch.
7.1 Causes of cloudy pool water
- Cloudy water can have many causes. The most common include
- Missing or insufficient disinfection
- Bacteria and organic substances multiply
- Incorrect pH value – impairs the effect of chlorine
- Algae growth – often starts invisibly, makes the water milky
- Insufficient filtration – fine particles remain in the water
- High bath load – brings in dirt, oils and skin oils
- Too many dissolved solids – e.g. due to hard water or overdosing of chemicals
7.2 First measure: Check water values
Before you intervene with chemicals, you should check the water values:
- pH value:Ideal 7.0-7.4
- Free chlorine:** 0.5-1.0 mg/l
- TA (alkalinity):** 80-120 mg/l
If the values are not in the ideal range, you must first adjust them – e.g. with pH-Minus liquid. A pH value that is too high is often the cause of a poor chlorine effect and therefore also of turbidity.
7.3 Carry out shock chlorination
If the water is very cloudy or smells musty, shock chlorination can help. It eliminates bacteria and organic contamination. Use chlorine granulate Active 65 and dose according to the manufacturer’s instructions with the filter pump running.
7.4 Optimize filtration
A lot of cloudiness is caused by insufficient filtration. Check the condition of your filter medium – we recommend backwashing sand filters and replacing cartridges and filter balls if necessary. Allow the filter system to run for at least 24 hours after the shock treatment.
7.5 Targeted use of flocculants
If the filter is unable to capture fine particles, a flocculant can help. It binds the smallest suspended particles into larger units, which are then absorbed by the filter. Important: Only use with sand or glass filters – not with cartridge filters.
7.6 Prevention for the future
To keep your water permanently clear:
- Check the water values 2-3 times a week
- Operate the filter system for at least 8 hours a day
- Regularly backwash or clean the filter
- Use algaecides as a precaution
- Shower off bathers before swimming
Conclusion
Cloudy water is no reason to panic – the problem can usually be solved quickly. What is important is the right combination of water analysis, targeted use of chemicals and good filter technology. At chlorladen.ch you will find all the products you need to keep your pool water permanently crystal clear.

Algae are one of the most common problems in pool maintenance – especially when temperatures rise and the pool is used intensively. They multiply rapidly, turn the water green, make surfaces slippery and have a significant impact on water quality. But there is good news: You can effectively prevent algae growth with a few preventative measures. In this article, you will find out how algae develops, how you can nip it in the bud and which products will help you – with two specific recommendations from chlorladen.ch.
8.1 How does algae form in the pool?
Algae are plant microorganisms that enter the pool water via the air, rain or bathers. Under favorable conditions – i.e. warm water, sunlight and insufficient disinfection – they thrive particularly well. Typical signs:
- Greenish, yellowish or black water
- Slippery pool walls or floors
- Cloudy water despite functioning filter system
Algae are particularly prevalent after thunderstorms or periods of heat.
8.2 Preventive water care is the key
Algae control does not begin with visible infestation. The best measures are
- Regular water analysis: Check the pH value and chlorine at least twice a week
- Optimal disinfection: Keep free chlorine constant at 0.5-1.0 mg/l
- Keep pH value stable: Ideally between 7.0 and 7.4 – if there is a deviation, use pH-Minus, for example
- Daily filter runtime: At least 8-10 hours at high temperatures
8.3 Use of algicides
As a preventative measure, we recommend the weekly application of an algaecide. Algizid Ultra is particularly effective against green, black and vertical types of algae. It contains no metals, is foam-free and does not attack films and technology.
Dosage: 50-100 ml per 10 m³ of water per week – best added in the evening while the circulation is running.
8.4 What to do if an infestation starts?
If the first signs are visible (slight green coloration, slippery spots), act immediately:
1. Carry out shock chlorination with chlorine granulate
2. Double dose algaecide
3. Run the filter continuously for 24 hours
4. Thoroughly brush the pool
5. Check the water values again and readjust if necessary
Conclusion
Algae are annoying – but not unavoidable. If you check your water regularly, filter it sufficiently and use high-quality products, you have the best chance of enjoying an algae-free bathing season. chlorladen.ch offers you everything you need from a single source – from algaecides to water care kits.

Chlorine is still the classic pool care product – but there are other ways to keep the water clean and hygienic. More and more pool owners are looking for alternative methods to protect sensitive skin, avoid the smell of chlorine or create a more natural bathing experience. In this article, we show you the most common alternatives to classic chlorine treatment – including their advantages and disadvantages as well as product tips from chlorladen.ch.
9.1 Why alternatives to chlorine?
Although chlorine is effective, it can cause skin irritation, eye burns or allergic reactions in sensitive people. The typical swimming pool odor is also not everyone’s cup of tea. In addition, chlorine products are complex to store and handle. If you want to avoid these disadvantages, there are now a number of alternatives – for both private and public pools.
9.2 Oxygen-based water treatment
Active oxygen is the best-known chlorine alternative. It has a disinfectant effect without irritating the mucous membranes and is completely odorless. Ideal for smaller pools or whirlpools. However, it must be combined with an algaecide as the effect is not as long-lasting as with chlorine.
9.3 Salt water electrolysis
With this method, sodium hypochlorite – a chlorine compound that acts directly in the pool – is produced from natural salt in the water using an electrolysis process. The advantage: chlorine no longer needs to be dosed manually. The salt content is approx. 0.4-0.5 %, which corresponds to the natural salt content of tear fluid. Important: The technology is somewhat more expensive and requires special cells and corrosion-resistant pool components.
9.4 UV disinfection
Here, the water is passed through a UV lamp, which destroys germs and microorganisms. UV systems are very effective, but usually require additional disinfection (e.g. with a small amount of chlorine or active oxygen) as they do not have a depot effect. Ideal for allergy sufferers or skin-sensitive users.
9.5 Copper-silver ionization
A rather rare but interesting method: copper and silver ions have an antibacterial and algicidal effect. The technology is often used in combination with other systems, as the effect is slow. Important: Regular monitoring of the ion concentration is necessary to avoid deposits.
9.6 What suits my pool?
The choice of the right alternative depends on:
– Pool size and design
– Skin sensitivity of users
– Budget for purchase and running costs
– Maintenance costs
Active oxygen systems are well suited for smaller pools or whirlpools. Larger pools are more likely to benefit from salt electrolysis or UV systems in combination with minimal chemicals. You can find water care products based on active oxygen at chlorladen.ch.
Conclusion
If you want to do without chlorine, you now have more options than ever. Choosing the right method depends on your personal preferences, your pool type and the amount of maintenance required. chlorladen.ch offers you a wide selection of chlorine-free alternatives – for a gentle, skin-friendly bathing experience.
