Hi all, have been battling algae for 3 years now. Always did what pool store recommended, would not see if for a few days then bam back again. Same thing all year this year until I found this site. My water looks FANTASTIC, best it has in years however....I still have not passed an overnight chlorine test. I have been slamming the pool but I suspect my trouble is behind my light. Am working on getting that out and cleaned. When I went out there this morning I did once again see a small spot of algae. Test results are as follows.
I have been shocking up to mustard algae levels according to the chart. First night chlorine took a nose dive, brought it back up and it lost about maybe 3 or 4 ppm overnight. I have a lot of gray stuff on the bottom of the pool that I am guessing is dead algae. Let it slack until I can get my light out, seems to be stuck then will bring it up again. Do I seem to be on the right track? My CA is high I know but I hope to get through this year (closing in two weeks) and will drain at beginning of season next year. Any advice would really be appreciated.
