HTH Chlorine Granules are a readily soluble chlorine granule based on calcium hypochlorite (unstabilized chlorine), which means it does not form a chlorine lock in your pool. The granules are manufactured in the USA and have been granted approval for use in drinking water, ensuring the highest quality chlorine.

These granules can be used in all types of swimming pools, both for daily chlorination and periodic shock chlorination.

HTH chlorine is the world's most widely used product for ensuring clean bathing water in both private and public swimming pools.

By always ensuring you have between 1-3 mg/l of HTH chlorine and a pH value between 7.0-7.4 in your swimming pool, you will always have crystal-clear pool water.

Saniklar pH-Minus is used to lower the water's pH level.

Perfect pool water requires a pH level between 7.0-7.4. A pH level that is too low can make the water aggressive towards the pool's metal components, while a pH level that is too high can lead to calcium deposits and cloudy, milky water. Within the pH range of 7.0-7.4, the water is slightly basic, allowing for the optimal effectiveness of chlorine addition.

Saniklar SunFlok Magic Rolls is a slow-dissolving flocculant that is placed in the skimmer basket and dosed gradually over several days. A sand filter functions optimally when pool water is continuously supplied with flocculant.

The product gathers particles in the water that are too small to be filtered by the sand filter into larger flocs that can be retained by the sand filter. These particle flocs are easily removed from the filter by backwashing.

The product is suitable for all pools with glass or sand filters, whether chlorine-containing or chlorine-free care products are used.

Saniklar Winter Clean acts as an effective preservative, used alongside the disinfectant for winter protection of all types of pool water. At the same time, the product ensures the hygienic quality of your pool water.

The product is added to prevent algae growth and to avoid calcium and metal deposits on the pool's bottom and sides. In this way, spring preparation of your pool is reduced to a minimum.

Saniklar Super Kleral – Effective Protection Against Algae and Scale

Saniklar Super Kleral is a modern and highly effective combination product that reduces the risk of algae growth, clumps dead algae together, and minimizes the precipitation of lime and metals in pool water. This helps the filter efficiently capture and remove broken-down algae.

The product is compatible with all disinfectants, except for BAQUACIL PHMB 2 in 1.

Saniklar Pool Defense – Effective Protection for Your Pool

Saniklar Pool Defense offers several benefits:

• Removes metals from pool water
• Dissolves lime and metal deposits on the pool floor and walls
• Protects salt chlorinators

In both Denmark and southern Sweden, water is often hard, meaning it contains high amounts of lime. Additionally, the water often contains iron, which, together with lime, can precipitate in the pool and form stubborn deposits on the walls and floor.

When iron oxidizes in the pool, it turns into ochre, creating brown stains that cannot be scrubbed away.

With Saniklar Pool Defense, you prevent the formation of lime and iron deposits, keeping your pool clean and well-maintained!

It is essential to measure and, if necessary, adjust the alkalinity during water replacement or if issues arise in maintaining a stable pH level between 7.0-7.4, especially after heavy rainfall. The alkalinity should be within the range of 80-120 mg/l.

You can measure alkalinity using test strips or a SmartTest.

Saniklar Chlorine Stabilizer is granulated cyanuric acid that prevents the sun's UV rays from breaking down the chlorine content in the pool. This product is intended for use in outdoor pools, and optimal effectiveness is achieved at a concentration of 25-40 mg/l.

Saniklar Clear Water is a liquid flocculant used for rapidly improving the clarity of pool water.

The product acts like a "magnet," gathering the fine suspended particles that make the water appear cloudy and murky. These particles are then grouped into larger flocks, which can be trapped in a glass or sand filter or vacuumed from the pool's bottom, where they have collected. The particle flocks are easily disposed of from the filter during backwashing.

The product can be used in all types of pools, whether chlorine-based or chlorine-free maintenance products are used.
