Continuous use of stabilised chlorine products or overdosing with pool stabiliser.
HTH® recommends that the stabiliser level never exceeds 50ppm.
The only solution is to “dilute” the stabiliser level by removing some of the water and topping up with fresh water:
- The simplest and most economical way is to drain a portion of the pool water by setting your pool filter onto “waste”. Approximately a quarter of the pool water should be sufficient in most cases although in severe cases of stabiliser levels (over 120ppm), additional water may need to be removed.
- The pool must then be topped up with fresh water.NB: Either the use of HTH® Granular+ Mineralsoft Chlorine™ or HTH® Non Stabilised floater is recommend for sanitizing the pool to prevent increasing levels of stabliser.
If you choose not to reduce the stabiliser level in your pool water:
The condition of your pool water may not improve.
All dosages are based on an average pool with a capacity of 50 000 litres. Adjust according to your pool size, regional variations and weather conditions.
