Troubleshooting Guide Probable cause Low Total Alkalinity pH BOUNCE EHDCE TRERTMENT a WATER BALAMEE www fi clor co uk Troubleshooting Guide pH BOUNCE Low total alkalinity can arise from a number of causes The make up fresh mains water may have a low total alkalinity usually associated with a soft water source However in areas where mains water with a low pH and low total alkalinity has been found to be aggressive towards old lead pipework systems the water supply companies have artificially boosted the total alkalinity with chemical additions It is therefore now unusual to find mains water with an excessively low total alkalinity amp low pH pH reducing chemicals such as dry acid or hydrochloric acid may have been dosed incorrectly If these materials are dosed in one spot and not distributed evenly around the pool an area of high local acidity will be created The bicarbonates cannot survive in these areas of high acidity low pH and some total alkalinity will be destroyed Please see the Troubleshooting Guide for High pH for instructions on dosing pH reducing chemicals E High local acidity be caused by turning the circulation off when slow dissolving chlorine tablets are being used in the skimmer pump basket or in a circulatory feeder device A solution of low pH and relatively high chlorine content will be formed in these stagnant conditions which wil
