Been religiously testing and dosing my pool since I slammed it last October. We had the first really hot few days in a row with over 100 degree days. Water is still in the 80s. Yesterday evening I noticed a very small green spot in a top corner just at the water line, maybe an inch or 2 down. Tested chlorine, 6.5ppm. Raised to 8.5, and did an OCLT. Lost absolutely no chlorine overnight. Tested 8.5 before the sun hit the water. Normal chlorine use is about 1.5ppm per day if no one swims. Have not fallen below min. Levels post slam last year.
With the sun blasting shallow water is a tiny spot of algae enough to necessitate a slam? Hard to judge since it already passes the OCLT without a problem. Water is clear as ever.
Only my second year with a pool and I’m looking for perfection. Not sure what is normal.
