Establishing and keeping the correct water balance is important for a number of reasons:
Protection of pool and plant room equipment
Water quality and appearance
Makes it easier and less time consuming to look after the pool
Some people believe that keeping the right pH is all that is needed to achieve the correct water balance; this isn’t the case and although pH is important there are other factors that also need to be considered:
TDS (total dissolved solids)
Remember that water balance can change with dilution of the pool by rainwater, the introduction of fresh water to top the pool up, the chemicals used to oxidise and sanitise and by bathers using the pool – so keep checking the levels throughout the swimming season.
