My pool has been doing great for a couple of years with no algae outbreaks thanks to you guys. However, today, when I was about to jump in, I noticed several yellowish brown patches. ( see pics). They are a little slimy and rub away with my finger Is there anything other than algae this could be? I’ve been trying to raise my CYA a bit because I discovered last summer that the recommended level was too low and meant adding a bottle of 10% chlorine every other day. I saw someone on here saying they tried raising theirs, and it worked. Seemed to work for me, as well, last summer. Anyway, I have been using the pucks instead of bleach to raise the CYa for a week or two. The FC level is staying quite high With the pucos. Wouldn’t algae eat it away pretty quickly? FC was 11 two days ago and is at 15 today, with the three pucks almost dissolved.
Here are all my numbers:
FC 11
Ph 7.6
TA 70
CH 220
CYA 70
thanks!
