Hi all! New to this group and having trouble with algae on the walls. One whole wall seems to be worse than the other, but luckily it is not the whole pool. We have had the pool a little over a year and never had algae or cloudy water, just battled high CYA last summer. I have a Taylor kit and did a 30ppm shock Sunday night, if I did it right. I used 5 gallons liquid chlorine, and made sure my pH was good first. I am still brushing off some algae daily. My levels last night were: FC/TC level says 10, pH 7.8, CYA 60 and TA 90. I just ordered the FAS/DPD addition for my Taylor kit. Hope to have it soon. The water is clear, just not sparkling. Any suggestions? I maintenance regularly, look at the pool daily, empty baskets and skim top surface daily, brush the pool and use the robot weekly. We keep 3 pucks of chlorine disks in the feeder. TIA!
