Hello everyone. I have been a lurker here and over at PF for a few years. Never really had a problem, but I come here often to learn. Right now I think I am battling mustard algae and I don't know how to beat it. I have tried several times to get rid of it to no avail. I believe I had mustard algae last year, but couldn't get rid of it. I am determined to do it this time. Here are my current numbers taken with K-2006 test kit.
FC - 19
CC - .5
PH - 7.3 (taken 1 1/2 weeks ago before I started shocking)
CYA - 30-40
TA - 160
Calcium - 200
I started shocking the pool on about June 30 to 18ppm. I bring it back to shock levels 3 times a day. Needless to say I've used a lot of bleach. The water is sparking clean, I just get gatherings of brown/yellowing "dust" in the divets of the pool every day. I have been vacuuming and brushing the sides once a day. I keep the solar cover on at night so we can try to enjoy what little summer we are having (current temp is 80). I checked the levels last night at about 10pm, and my FC was 18.5. At 6am it was down to 14. I am at my wits end with this stuff and don't know what to do. To make matters worse, we are leaving town on Sat. morning and not returning until Wed. evening. I thought when I started this I would have it well under hand by now. It seemed like there was less algae in the pool after the first few days, but then we had a thunderstorm on Monday and I'm right back where I started. I even checked the levels after the storm and brought it right back up to where it was supposed to be.
Any advise would be appreciated. I am thinking of trying the borates thing. Any suggestions?
Thanks!
