Last sunday I installed a solar cover on our 18x36 26KG IG. Prior to the solar cover I had been consuming 2~3PPM/day with the CYA @~50.

The past week with the cover on I am down to 1~1.5PPM/day!

With the cover, I can keep the water temperature up and literally cut my bleach costs in 1/2! Why didn't I do this sooner?
