Long story short - I'm having trouble with mustard algae - clearly yellow, on verticals, in shade. But am losing massive amounts of FC during the day while I'm at work. Not sure if that's Phoenix sunlight at work... and if I'm going to have to find a way to keep FC up during the day?
Night 1: Brought CL up to 25.5 in the evening. Overnight lost 1.5 CL and CC 0.5 (CL = 24)
Day 1: Brought CL up to 35 before I left for work... and was down to CL of 7 (CC 0.5) when I got home in the afternoon. (lost 28 CL!)
Night 2: Brought CL back to 28 in the PM, Overnight lost 1.5 CL (CC 0.5)
Day 2: Brought CL up to 35 before I left for work... and was down to CL 8.5 (CC 0.5) when I got home this afternoon. (lost 26.5)
Is this normal in Phoenix?
