I love the TFP method, I used the BBB for 5 years until I recently had my pool replastered. Now I have to submit water once a month for testing to keep my warranty. I have been keeping my SWG pool at FC 5-7, CYA 70-80, pH 7.5-7.8, TA 70-90. The reason for the high FC is that I live on a golf course with a slow moving stream between me and the golf course and I've had a few run ins with algae. I think the phosphates from the fertilizer being blown with machines on fairway toward my pool seem to cause algae blooms. At any rate the new chemical requirements are causing me problems. I'm supposed to keep my FC at 1-3 the CYA 40-60, TA 75-90 and pH 7.2-7.6. I've been using what I thought was a non-chlorine shock because I've been afraid of getting an algae bloom. But, it turned out to be 37% chlorine. The pool company says high chlorine will cause staining on our new Sunstone Golden Pearl. How can I keep my warranty and keep from having algae? And how do I get my pool stats at the bottom of my posts?
