Swamp Fever

Long story short, my pool went unused in 2019, and was uncovered from the end of the 2018 season until November of 2019. While it was uncovered, I spent about an hour every warm day scooping debris out. I opened it up last weekend, knowing I would have a disaster to deal with. My local pool store sold me a chemical called "swamp to swim" and provided detailed instructions for using it, in the hopes of getting me water clear enough to see what I'm cleaning. My son and I have been outside vacuuming and scooping with a leaf net every day until the water gets too low for the vacuum to operate. I tried the 'leafgulper' but one of the wheels broke off, and we're not able to use it anymore. We've certainly made progress, as the wastewater has been gross and the baskets constantly needing to be emptied of leaves, itchyballs, and assorted crud. But we're still not clear enough to see the bottom. The smell has dissipated, at least. We were advised not to turn on the filter, as the swap to swim would clog it. Any ideas on what else I can do? I did put six chlorine tablets into the floater, and I have several chemicals left from previous years, just not sure what to use. I'd like to avoid draining the pool, as I have been warned repeatedly that it will collapse.
Good luck with your pool you just reminded me of my leaf gulper. I don't have a major swamp but that will help especially since the water is indeed low.
 
My heater was installed today, which made servicing my filter and pump awkward. The pool still isn't clear. I just backwashed and recharged my filter, set the pump for 1500 RPM, and I'm at 2psi.
My last four FC/CC tests were 21/1.5 @10AM Sunday, 23.5/1 @9PM Sunday, 23.5/0 @1:30 Monday and 20/0.5 @8PM Monday.
 
Disassembled and cleaned the filter today (taught my son how to do it), fully recharged it. Water still isn't clear. My leaf rake is no longer doing anything, but the robot is picking up a lot of silt. I am going to need to get some more DE soon. Now I've used 54lbs of the stuff in a month. At 2200rpm, my filter guage says 8psi, but my salt cell is showing no flow. I do feel water coming through my return.

Still not clear, but certainly progressing. I can see the pattern on the second step, and the outline of the third. Still quite cloudy, and the robot is still filled with whitish silt. The filter clogged again after over 24 hours but still showing 8psi@2200. I don't feel any flow at the returns, I don't understand why. I put the filter on recirculate overnight, and I'll backwash and recharge in the morning.

If your filter is clogged and you can't detect good flow, your gauge is bad. PSI is essential for managing your pool. Replace the gauge. TFTestkits has a nice one that is glycerin filled (freeze proof down to about -10 F).

I just backwashed and recharged again. The pool is certainly looking clearer; I can make out my third step and I can see the robot at the bottom of the shallow end. Water is still cloudy, and the deep end is green. I turned my SWG on, and I'm also dosing with the liquid chlorine to comply with the SLAM from the app.

Jersey - I would recommend keeping the SWG off until the SLAM is done and you're ready to go back to maintenance levels of chlorine. It won't really generate enough to be of much help and it might make figuring out how much liquid chlorine to add difficult - you don't want to overshoot your FC target, or there could be issues down the road.
