When I got home today, I noticed that my pool turned from green to blue. A bit cloudy, but blue finally. Apparently the Stain Free did it's job. There are still some stains left, but its about 90% fixed. I figure I will do another round in a few weeks, but for this weekend I need to swim! The online directions say to vacuum pool and backwash after 24 hours, then balance as needed. I just passed the 24 hour mark, and ran my numbers. They are: PH= 7.2, Alkalinity= 120, and Chlorine= 0. I now want to get everything balanced for the weekend and need to raise my chlorine. The older bottle of stain free I have says to not super chlorinate for 72 hours after treatment. The newer one says not to add chlorine or "shock" until pool has been vacuumed and backwashed after 24 hour period. Thinking I would be cautious, I just put 4 98% Trichlor pucks into my skimmer hoping it may give me a chlorine level, without going overboard. The recommended amount of tabs is 8 to achieve 1-1.5 PPM increase in a unbalanced pool. In an earlier post, PoolDoc said to not add tabs to my skimmer and just use Cal hypo through it. Should I take the tabs out and add a small amount of cal hypo, or just keep them in and monitor the situation? Thanks.
