Hey all! We recently had a lot of rain over two weeks, and i got a bit of cloudy water and i think some algae. I started a SLAM on Sunday. Cya is at 40.
I am keeping the fc at 16 per the chart. Vinyl aboveground, sand filter. I checked it last night and somehow the fc was at 21.5. I checked in the morning and it was 20. It did have some sun exposure so i think i only lost 1 ppm last night. Cc are .5 or less, water is clear. I have scrubbed skimmer, ladder, brushed twice a day during the slam and vac to waste anything on the bottom.
So here is my problem: I had my wife check the water 6 hours after I did, and the FC dropped to 8? Whats going on?
Full numbers as of right now
Ph 7.6 (i think, fc is a little high for accuracy.)
Using a tf100 test kit i got here last summer.
