2nd year pool owner. First year on TFP. 6 days into my first SLAM. Pool water looks great. Overnight loss test last night showed 0 FC loss. CC has been less than .5 since day 1 of SLAM. CYA is at 80 so I’ve had to be keeping high FC for SLAM. At least 31FC but the past 36 hours I’ve been at 38 or higher. But I still have these spots of this yellow / brown ish stuff in the bottom of the pool. It’s only on the bottom in the small creases in the vinyl liner. I can run my robot vacuum and it’ll be gone. If I brush it with the brush it just poofs and goes away. Then 24 hours later it shows up again. Am I still dealing with active algae or something different? Shall I stay at the higher FC or go to full 60% or CYA for 24 hours?
Thank you in advance.
