Ok, did as instructed. Got pH down slightly, then added 5.4 gallons of bleach. Didn't test FC until next morning, but read 26.5ppm. That afternoon it was 21.5ppm. The next morning (this morning) it's 13ppm. Tested pH this morning and got 7.4. Pumps been running non stop for a couple weeks now. Not going to lie, starting to get discouraged. Still the exact same pea soup. How will I know when it's working? Will it simply consume less FC or will I see a visible change initially? Off to WalMart for more bleach? again, thanks very much.
