AquaForte Alg-Stop Liquid 2.5L – Effective solution against stubborn filamentous algae

Prevent and control stubborn filamentous algae in an effective and controlled manner with AquaForte Alg-Stop Liquid. This powerful liquid algaecide is specially developed for ponds and swimming ponds where a stable biological balance is essential. Thanks to its unique mode of action, Alg-Stop tackles the cause of algae growth without immediately removing nutrients from the water.

Targeted action against algae – without disrupting the ecosystem

Instead of extracting nutrients, Alg-Stop adds a specific active substance that is absorbed by algae. This substance blocks the uptake of essential nutrients, effectively halting algae growth. At the same time, the product penetrates deep into the algae structure and attacks the calcium skeleton. As a result, the algae break loose and can be easily removed by the filter system.

This approach ensures:

• Targeted control of filamentous algae
• Minimal disruption of the biological balance
• Long-lasting clear and healthy pond water

Optimized for structural maintenance

AquaForte Alg-Stop Liquid is not only suitable for acute algae problems, but also for preventive use. By dosing monthly, you prevent algae from regaining control and keep your pond in optimal condition.

Dosage:

• First 3 weeks: 100 ml weekly per 3,000 liters of pond water
• Maintenance: 100 ml monthly per 3,000 liters
• In case of heavy algae growth: apply a double dose

After rainfall or water replacement, it is recommended to redose for a stable result.

Smart use in automated systems

For maximum efficiency, Alg-Stop Liquid can be excellently combined with automatic dosing systems such as the AquaForte DosaTech. This ensures a constant and accurate dosage, resulting in more stable water quality and less manual maintenance.

Important usage guidelines

• Do not combine with other algaecides
• Regularly check water parameters
• Phosphate measurements are not representative after use
• Suitable for ponds and swimming ponds

W’eau pH plus powder - 5 kg is a product designed to increase the pH level of pool water, so that it falls within the correct range for safe and comfortable swimming. Here are the main features and directions for use for W’eau pH plus powder:

**Why is the pH level important?** The pH level of pool water is a crucial factor in maintaining water quality. A good pH level is usually between 7.2 and 7.6. Maintaining the correct pH level is essential to prevent the water from becoming too acidic or too alkaline, which can irritate the eyes and skin and affect the effectiveness of disinfectants.

**Directions for use:**
1. Always start by measuring the current pH level of the pool water with a pH test kit.
2. Read the recommended amount on the packaging of W’eau pH plus powder required to adjust the pH level. Add the correct amount of powder to a bucket of warm water or pool water.
3. Mix the powder thoroughly until it is completely dissolved.
4. Pour the solution evenly over the pool surface.
5. Allow the water to circulate well to ensure that the product is evenly distributed.

**Important note:** Never use W’eau pH plus powder at the same time as other chemicals, such as chlorine. Always add the powder to the water and never the other way around.

**Safety instructions:**
- Always store the pH plus powder in a safe, dry and cool place, out of reach of children and pets.

When you use W’eau pH plus powder as prescribed, you can adjust the pH level of your pool water to ensure that it is within the correct range for a comfortable swimming experience.

sera pH/KH-minus

Some fish species, such as discus and scalare fish, thrive best in very soft water, especially for breeding purposes. However, when keeping other fish species, the water may have too high a carbonate hardness (KH), or the pH level may have risen too sharply due to natural metabolic processes.

In such cases, sera pH/KH-minus offers a reliable and fast solution. The pH and KH levels are lowered and regulated quickly and accurately. This creates conditions that are suitable for the specific needs of the fish and contribute to their well-being.

Tip: For the permanent maintenance of tropical soft water conditions, set the KH to 4 dKH with sera pH/KH-minus and then place sera super peat in the filter.

Technical specifications:

• 100 ml: suitable for 400 liters of water
• 250 ml: suitable for 1000 liters of water
• 500 ml: suitable for 2000 liters of water
• 2500 ml: suitable for 10000 liters of water
• 5000 ml: suitable for 20000 liters of water

W'eau TA+ is a product that increases the total alkalinity of pool water. Maintaining the correct alkalinity is essential to keep the pH level of the pool water stable. Here are the main features and directions for use for W'eau TA+:

**Why is alkalinity important?** The correct alkalinity in pool water helps keep the pH level stable, even during unexpected weather changes or the use of other chemicals. This contributes to the water quality in the pool.

**Directions for use:**
1. Always start by measuring the total alkalinity (TA) of the pool water using a pool water testing kit. An ideal TA level is usually between 100 and 150 ppm (parts per million).
2. Add the correct amount of W'eau TA+ powder to a bucket of warm water or pool water according to the instructions on the packaging. The required weight may vary depending on the desired adjustment of the TA level. Generally, you can use the following rule: 150 grams of TA+ powder per 10 m³ increases or decreases the TA level by approximately 10 ppm.
3. Make sure the powder is completely dissolved in the water before spreading it evenly over the pool.

**Important note:** Never add more than 300 grams of W'eau TA+ powder per 10 m³ of pool water during a single treatment.

**Safety instructions:**
- Never use TA+ powder at the same time as other chemicals, such as chlorine. Always add the powder to the water and not the other way around.
- Always store the TA+ powder in a safe, dry, and cool place, out of reach of children and pets.
- Always rinse an empty package thoroughly with pool water before throwing it away.

**Features of W'eau TA+:**
- Approved for use in swimming pools.
- Available in different package sizes, including 1 kg and 3 kg.

By using W'eau TA+, you can adjust the total alkalinity of your pool water to maintain the water quality and keep the pH level stable. The proper use of this product contributes to an optimal swimming experience in your pool.

The HRS Flocculant 8 Cartridges 1 kg has been developed to remove fine, suspended impurities that are normally too small to be captured directly by the sand filter. The flocculant binds these small dirt particles together into larger flocs. This makes it easier for the sand filter to filter them out of the pool water.

For fine suspended dirt particles

Even when the water levels are good and the filter system is functioning correctly, very small dirt particles can remain in the pool water. This can make the water look less clear or slightly cloudy.

The HRS floc cartridges ensure that these small suspended particles are bound together. The formed flocs are larger and can therefore be stopped by the filter material.

Simply via the skimmer basket

It is easy to use. Place a floc cartridge in the skimmer basket. While the pool water is circulating, the product gradually dissolves and the flocculant is distributed throughout the pool. The bound dirt particles are then captured by the sand filter.

Only suitable for sand filters

According to HRS, these floc cartridges are intended exclusively for use in swimming pools with a sand filter system. They are therefore not intended for use with, for example, a cartridge or pattern filter.

8 cartridges of 125 grams

The package has a total content of 1 kg and, according to the current HRS catalog, consists of 8 cartridges of 125 grams each. This makes the cartridges easy to use individually without having to measure out loose flocculant for every treatment.

Important points

• Binds fine, suspended dirt particles together
• For impurities that cannot be filtered directly
• Supports the clarification of pool water
• Specially for use with sand filters
• Easy to place in the skimmer basket
• Gradually dissolves during water circulation
• Dirt flocs are then captured by the sand filter
• For easy and measured application
• Package with 8 floc cartridges
• Weight per cartridge: 125 grams
• Total content: 1 kg
• Store dry and well sealed
