I have a roughly 12,500 gallon bean shaped pool with a DE filter. This is my first time owning a pool and I did not winterize it and let it sit until a few months ago. Since then I've done all I can to get it back to what it once was. I first skimmed it and then the bottom which had a ton of leaves and gunk then shocked it with about 8lbs of shock which turned it from a dark green to a clearish greyish blue. Then scrubbed and flocced it. The floc worked but my manual vacuum wasn't working. No idea why. It's still not. I have it set to waste and one of the skimmer basket lines blocked with a tennis ball and there is no suction. Line isn't blocked as I accidentally sucked a face towel through it and it got caught by the pump skimmer basket. Well I tore the backwash hose and when replacing it I broke the outlet pipe so I had to mend that with epoxy. While that cured for a week the pool got bad again so I shocked it, added clarifier and when it finally was able to "waste" water I ran the filter because the water was cloudy which upon reading later was a huge mistake. The walls felt slimy so I scrubbed them again and added a whole gallon of algaecide. Then another bag of floc so I can see what I'm doing. But nope still cloudy. Upon running the filter it goes up to 2 which is 30psi which I've read is high. I've cleaned the filter multiple times but every time it goes back up to 2 within a few minutes. The only time it didn't was when I didn't add DE to the filter after cleaning it. I've already spent hundreds on this and I honestly can't afford much more. Did I just irreversibly damage everything and all hope is lost or can anyone help? Do I just need to drain or are there some cheap fixes or helpful tips you can give me I can try? Any help would be much appreciated. Is there any way to break down the floc without having to vacuum? Oh and all the stuff I listed doing was in the span of like 3 months.
