Although this is my first post, I've been lurking for quite a while. With the help of this site, I was able to defeat an algae bloom near the end of the season last year and we coasted through the rest of the summer. A good ending last year but not a good start this year. We set up the pool just before Memorial Day. Since then the water has had a slightly greenish tint without the cloudiness we've seen with algae. I've had the SWG on for 5 hours a day starting at approx. 7:30 a.m. The first 4 days we had no swimmers; since then no more than 4 kids at a time for less than 2 hours a day, some days none. I shocked with 43 oz. of 6% Fri. night, then the same last night, followed by 96oz. this morning. I only tested the water today (couldn't find the kit), here are the results from 2 tests, 6 p.m. and 7:30 p.m.:
FC 11.5 10.5
CC <.5 <.5
pH 7.5 7.3
TA 40 40
CH 70 70
CYA don't have everything needed to measure that
I've brushed at least 6 times today and I can stir up a little something but not enough to change the clarity of the water. When I clean the filter it's just slightly brown now but it was really ugly the first few days (brown, not green). We also have a lot of cotton from our neighbor's cottonwood. I try to get as much of that as I can with the net.
So where do I go from here? By the way, I'm off work all week, so I've got time to care of this.
