With the temps in SE Texas reaching 90F, I have just started getting CH flakes from the returns.
My chemistry today:
I have been struggling with hardness (fill water is 130 ppm). When the CH was 450 in March, I replaced 40% of the water. Pool will be one year old in July.
I checked the chlorinator today and it looked clean. Only some buildup on the ends, which I washed off.
Any ideas on keeping the CH down (don't want to drain my pool every quarter) and reducing the flakes.
