Just took off solar cover. Water is balanced and FC held at 12.5 for three days with cover on! Mustard algae is gone but discoloration at deep is still there. I crushed Vitamin C tabs, put in a sock and tied to my pole and brush. After 10 minutes, the stain is substantially lighter. Now what do...

FC held over night at 18. I will still hold higher FC levels for the week (12 -14). I guess I'll start to bring my CYA levels up to 65 -70 now. I'll try the vitamin C as soon as I can get some. Here's a pic of the discoloration of the floor in my deep end. It's more at the bottom of the picture...

Still shocking after 48 hours to around 20 FC! CYA is about 40. Lost 3 on the overnight test for FC both Sat and Sun morning. CC is almost zero. We did get an inch of rain but I did some rough calculations and for my 800 sf pool that would be about 500 gallons of rain (not enough to reduce FC...

OK, the TF100 kit just came and here are the results: FC = 5 CC = 0 pH = 7.6 TA = 100 CH = 320 CYA = 35 The CYA is way lower than the pool stores were telling me. I did it twice to make sure. The pool calculator says to add 10 lbs of stabilizer. I'll add half that for now in a sock in the...

Thanks for everything. Now I just await the test kit. Then I can accurately shock. With the higher chlorine levels we have kept for a few days, it appears that the little brown/yellow spots are starting to fade. I hope a good shocking will make 'em disappear and we won't lose too many days of...

Update from pool store...Total chlorine 5.5, free chlorine 4.7. I orderd test kit from tf test kits.

Ok...my bad. I'm only testing for total chlorine with my kit (DPD). I'm going to get a new one this afternoon so I can test FC and CC. CYA is confirmed at 60. I can't seem to get a decent picture of the stains/spots, but I'll keep trying.

Thanks! Do you think it's algae then? The part that puzzles me is that it won't brush off and the FC didn't drop overnight. The recommended shock levels are very high. I assume we cannot swim in the pool until FC comes down to 5 or so? We'll order the test kit so we can test for over 5 ppm.

Hi, Our pool is 3 years old and we have not had a problem with it up to this year. The pH bounces up but I keep it in check with muriatic as needed. We're new to the forum and have a problem. I'm confused if it is algae or possibly scale. FC = 5 CC = pool store says .1 pH = 7.2 TA = 90 CH =...
