Hi,
I have had a yellow / brownish spot near my main drain in my pool. The spot has been there for about two years before I knew about TFP. I did not think much of it in the past since I did overnight loss test and only lost about 0.5 on my FC.
What is the best way to determine what kind of spot I have? Sorry I did not include pictures but as soon as possible I can post. I have had proper FC levels for the past two years. Could it be mustard algae and what does it look like?
FC 20.0 (currently shocking pool)
PH 7.6
TA 80
CH 420
CYA 40
Any help is appreciated.
Dave
