I've got some nasty looking water going on in my pool. It sat neglected for at least 3 years and I think( key word think) got all the leaves and twice off the bottom. I thought I had the algae killed once before so I put alum in it and turned the pump off to let the dead algae settle but it turns out not all the algae was dead so now I have a bunch of dead algae and live algae floating about my pool. I've got the FC up to slam level and the PH is about 7.2. The sediment is so bad my pressure is high enough to need to backwards within a few hours.
