So I thought I might have mustard algae as I had two yellowish deposits on the floor of the deep end. I had been keeping my solar cover on, 24/7 as I was working and no one else was home, so I figured that didn't help matters as far as mustard algae was concerned.
In any event, I shocked my pool last night to 24 (based on a CYA of 40, which is a bit higher than my last reading of 30, but I don't have confidence in my last reading as it was 50 2 weeks ago).
This morning, I tested and was at 21.5, which was a 2.5 drop, but with no CC.
I brushed everywhere and the pool is definitely cloudy and I can see quite a bit of whitish residue. Is this probably algae? I can see the floor of my deep end, which is at least 10 feet down, but not as well as I usually can.
Also, I found a mouse and 2 frogs in my skimmers, would that have been enough to also cause my FC to drop in addition to algae? I forgot to check the skimmers last night, but the creatures were not there for more than 24 hours.
Should I keep my solar cover off until eveything clears? I hate to lose the warmth and chlorine. Plus, I have a clear cover, so it does a decent job of absorbing sunlight.
By the way, here are the last test measurements I had:
FC - 21.5
pH - 7.6(?) -- It was hard to tell and I understand the pH test might be unreliable if FC is over 10.
TA - 110
CH - 350
CYA - 30 (as I stated, it was 50 2 weeks ago, so I have my doubts about this measurement)
