Just one simple weekly treatment with our patented environmentally friendly formula tackles the problem at its roots. The layer of slime is soaked away from the surface and then rinsed away with the water. Moreover, it cannot re-form. The result is a spectacular reduction of bacteria in the water for which you only need a minimal amount of disinfectant! Even lime, the notorious destroyer of swimming pool equipment, is no match for the power of AquaFinesse.
