Use; pH Plus to increase pH - pH Minus to lower pH and Total Alkalinity - Total Alkalinity Plus to increase Alkalinity - Calcium Hardness Plus to increase calcium hardness
Everyone knows they have to use a sanitiser like chlorine or bromine to keep their pool water clean, however it is often the case that users do not realise that a poorly balanced pool will limit the effect of chlorine, and in extreme cases stop it working altogether! This can cause algae infested green water.
Alkalinity, pH and Calcium hardness should be regularly tested and balanced to allow the sanitizer to work effectively and to protect the pool and its equipment from long term damage due to calcium build-up or acid corrosion. Take a look at our Help and Advice section for more information on keeping pool water clean and clear.
