Rijo Anti-Limescale 1 Liter is a powerful liquid limescale stabilizer specifically developed to prevent limescale buildup in swimming pools. Hard water contains high levels of calcium and minerals that can deposit on pool walls, floors, pipes, and technical installations. This can lead to white deposits, a dull appearance of the pool, and reduced efficiency of the filtration system and heat pump.
With Rijo Anti-Limescale, you keep limescale particles in solution, preventing them from settling. This keeps your pool cleaner for longer and protects pipes, filters, and heat exchangers against limescale deposits. Anti-limescale products also help prevent blockages and loss of efficiency in pool equipment.
Protect your pool and equipment
Limescale is not only visible on pool walls but can also accumulate in pipes, sand filters, heat pumps, and other components of the pool system. By adding Rijo Anti-Limescale preventatively, the system continues to function optimally and you extend the lifespan of your equipment.
Benefits of regular use:
Prevents limescale on pool walls and floors
Protects pipes and filter systems
Prevents deposits in the heat pump's heat exchanger
Keeps pool water clear
Reduces the adhesion of dirt and minerals
Extends the lifespan of pool equipment
Suitable for all types of pools
Rijo Anti-Limescale is suitable for almost every type of pool and can be safely used in combination with various water treatment systems.
Suitable for:
Above-ground pools
In-ground pools
Chlorine pools
Saltwater pools
Polyester pools
Foil and liner pools
Spas and hot tubs
Easy to use
The liquid formula mixes quickly with pool water. Add the recommended amount while the filtration system is running so that the product disperses evenly through the water. For the best results, use Rijo Anti-Limescale immediately after filling the pool and then periodically, depending on the water hardness.
With the Kokido buffer solution, you ensure that your digital pH meter always provides accurate readings. This set contains two bottles of buffer solution with different pH values: pH 7 and pH 4.
