I have been doing pretty good at keeping the pool at the indicated 5ppm level, I add chlorine late at nigh, pump runs from 6 am til 4pm, but I have algae growing for some reason I can't quite figure it out.
CYA level was 45 back in May, and I thought that number would not drop, but anyways.
I need to increase CH to 150 correct?.
I am going to start slamming but can you please give me an idea as to what could be the problem.
Filter is showing 10 psi used to be at around 20 psi, I have not cleaned it since it was clean back in October and not used until april. I do backwash once a week or 2 weeks and recharge.
Thanks for your help.
