I have a 20x40 rectangular gunite pool approx 30000 gallons with
I use a taylor K-2006 kit to test the water. I read some of ChemGeek's posts and have intentionally kept PH low at 7.2 .
I have backwashed the filter and the pump has been running for about 36 hrs now but no improvement - the water is still cloudy with a bluish green tint.
I also have a problem with air bubbles in the return line. I have checked the skimmers and ensured all fittings are air tight. But I have been unable to locate their source. Anyone have any thoughts as to where the leak is?
I use an opaque (blue) solar blanket during the day to reduce evaporation and Chlorine dissipation but now I wonder if that is
aggravating the algae situation.
Your assistance is appreciated
