Re: My test vs pool store test.
Hmm, did not know that about the slightly dirty filter. Thanks for the tip!

A slightly dirty sand filter is a better (lower micron) filter than a clean one.db13berry said:The past two days I back washed 3 times each day. Prior to that, I backwashed 2 - 3 times a day depending on my time at home. Today I have only had time to back wash twice so far. This morning it was dirty and psi was up. This evening the psi wasn't up but I back washed anyway and the sight glass was mostly clean.
