Took me quite awhile to lower my water too from about the same stage as you. We have an outside trash can and I measured 6.5” of water in it from the rain. I am hearing a thunderstorm approaching now so hopefully the bleach and acid I dumped in did the trick for now. Walmart was completely out of the 10% pool chlorine I was buying so I am having to use just plain old bleach. I dialed up the erosion feeder so hopefully that helps. I’ve supplemented with tablets in the skimmers from time to time too.
