Hey TFP, I'm, stumped by a hot tub issue.
I'm treating a Sundance Optima and have a recurring issue with some cloudiness and scum around the water line. The photos attached were taken after a fresh ill and 3 uses with just 2 bathers so I don't think it's soap or detergent.
I been cleaning out the filters twice a week (replaced them once) and have tried using 2oz of 5in1 clarifier every day which has no effect.
I just had it tested:
Free Chlorine 5.91
Total Chlorine 5.91
pH 7.4
Alk 39
Hardness 118
CYA 32
no metals
Does anyone have recommendations to clear this up and keep it that way?
