BSI Pool Calc Free 1 litre

Is there too much lime in your swimming pool water?
Then you can reduce the amount of lime with the Calc Free descaler from BSI.

The amount of lime is expressed in hardness, so the harder the water, the more lime.
With a high hardness, more lime deposits form on the walls of your swimming pool, in your installations and filters. With the Calc Free you prevent this deposit of lime on your swimming pool!

Tip!: Test the hardness of your swimming pool water first with BSI Test Strips.
