HTH Super Kleral is a Non-Copper Algicide used to both prevent or Kill Algae. It also stops limescale build up as well as helping to prevent staining on pool walls and floor from metals in solution in the pool water

HTH Super Kleral Algicides are based in Polymerised Quaternary Ammonium Compounds (Polyquat), are non-foaming so can be used in swim spas, too, as well as having 15% active concentration level, which is 50% more than other algicides. HTH Super Kleral Algicide will not affect the pH level of pool water, but will work effectively across a huge pH range.

If you have Algae in your pool, first shock the pool with HTH Shock Powder to raise the chlorine level to between 5 & 10ppm. After 24 hours you can then add HTH Super Kleral Multi-Functional Algicide, following the manufacturer's instructions on the tub.
