I've been a member of this site for quite a while and although I don't post much I read everything I can when someone has a problem, so I've learned quite a lot. I stopped using pucks over two years ago on advice of this site and went to the BBB method. I am very happy with it. So as my title states I've had an algae bloom ( I'll tell you how I got there in a moment) and just want to check with you to make sure I am doing everything right. (I have read all the articles in Pool School and just re-read them again) The following numbers are off a TF100 test kit (another lifesaver):
Pool Size 17.5K In ground Pool with a 2.0 HP motor connected to a Purex Clean & Clear Plus Cartridge Filter
CH 500 (I know, way off)
So I have continued to brush every couple of hours and earlier today got my FC up to 28 (Shock Level) based on my CYA levels. This number I got from using the Chlorine/CYA chart. The last reading was tonight and that was 28. Filter running now 24/7, water is cloudy, and I am in the process of accomplishing the Overnight test tonight, just want to make sure I am on the right track. Please let me know if there is something else I should be doing.
Now for how I got to this situation, I was keeping my FC at 5ppm which is what the calculator stated I should be at, I installed a solar cover and while the deep end of the pool was crystal clear, because that's where the Polaris was, when I removed the cover at the shallow end there was green everywhere, is there a problem I don't know about with solar covers? I was really heating up the pool and cutting down on the addition of chlorine along with my water evaporation. I would like to continue to use the cover, but not at this cost. If anyone who has been through this can give me some advice it would be greatly appreciated. Thanks!
