I thought I was having an issue I bought some aqua chem algeacide 50% threw it in water became cloudy not colored. today it cleared a bit, added bleach waited 2 hours I was not where I should have been, took out my filter and had brownish soot all on filter. I had 2 spares Iv'e started using rinz n reuz filters. I checked the new filter 2 hours later more soot, cleaned out the canister put in a new filter again brought the pool to shock level. I'll test again at 7:30am and vac again but my water is clearing only a bit cloudy now.

You should post a full set of water test results, otherwise we are just guessing.

Using algaecide is almost never worth it. Also, we only recommend using polyquat based algaecides. The one you used isn't polyquat based.
