SCALE OUT

A treatment that removes limescale from the pool shell, the plumbing system and the filter media (flint, glass, etc.). It should be applied whilst the pool is full and left to work for 4 weeks, minimising the number of filter backwashes to ensure the treatment remains at maximum concentration and contact time; for example, it is best to carry out the treatment during the winter or at a time when filter backwashes are not required.

Dosage: 5 L/100 m3.
