HTH pH Minus Micro Balls for swimming pools should be used to reduce the  pH or Alkalinity when the levels are too high. The HTH pH Minus Micro-Balls allow the chemical to dissolve quicker than other pH Reducers, meaning no residue left on the pool floor, no wastage and faster treatment.

HTH pH Minus Micro-Balls will help correct high levels of pH (above 7.6) or alkalinity (above 160mg/l), using the fast dissolving Micro-Balls to quickly act in reducing the pH or Alkalinity. High pH or alkalinity will lead to problems with cloudy water and scaling of surfaces and pipework. High pH will make chlorine sanitisers less effective and high alkalinity can make it difficult to adjust the pH

HTH pH Minus Micro-Balls works to lower your pool waters pH balance using Dry Acid. Dose rate can be doubled in hard water pools. Available in 5kg tubs.
