I recently added a scale eliminator to our swimming pool (made up of a concentrated acrylic polymer complex) due to large amounts of scale buildup on the SWG that would quickly rebuild even after putting the cell in an acid bath.
Within 24-48 hours of doing this, the chlorine demand increased dramatically. Even with 40ppm CYA in the pool the chlorine will not hold up during the day (even with the SWG running 24/7). As a result, algae is starting to form.
The total chlorine was 0.6 and free chlorine was 0.4 at 6pm today.
This morning it was around 3ppm.
This pattern has repeated itself all week with the SWG running on full continuously.
PH and total alkalinity levels are within a normal range.
Does anyone here know what is going on, how an acrylic polymer complex actually works and (most importantly) what can be done to rectify the problem with chlorine that was induced by adding this wretched scale eliminator.
