Just found TFP a few weeks ago, and it has been a real education. Actually defeated the worst algae problem I've ever had to deal with, and learned why and how I've been contributing to the problem. I join all posters in expressing appreciation for all the expertise shared, and I also became a supporter- the only way I can say thanks since I'm a real Newbie with all questions and no answers.
So, armed with my TF-100 test kit and lots of liquid chlorine and bleach, I've been slamming my pool because of some light green coloration late last week. Here are my latest numbers:
Last night: FC: 26 CC: 0 CYA: 60
This morning: FC: 26 CC: less than .5, probably 0 (thought MAYBE I saw a bit of pale pink but 1 drop R-0871 made it completely clear ) CYA: 60
The only reason I'm not sure I can stop is that I thought I might still be seeing a tiny bit of a very pale green yesterday afternoon. Did my testing later in the evening and got those numbers. Pool looks good today and it has been abnormally cool here- High-upper 60s, low- upper 50s. I have been dealing with bad algae problems lately so the past improvements have been dramatic. I guess in the past when the pool looked like it did yesterday it only got worse, but that was before I discovered TFP. So, am I finished with the slamming for now, and just do my daily tests? I backwashed a few times and refilled with fresh water to start to lower my CYA which had been at 70 and is falling. (#*!Tablets)
I am now completely convinced about liquid chlorine and follow all the TFP guidelines, use Pool Math, etc. But I was proud of myself this spring when I stocked up on chlorine tablets and "Aqua Chem Shock Plus 4-in-1 Pool Shock" when Costco had a sale. Now I'm kicking myself. Has anyone come up with a use for this stuff? I am looking into the cost of CYA decreaser- I'll do the math to see if it makes any sense at all to use, but I hate to waste all of my bad chlorine. And are there rules about how to dispose of it? Too bad I'm no longer washing cotton diapers! Maybe I can donate it to a pool store.
