Hey! had a gorgeous pool just a few days ago. missed 48 hours of keeping up on my chlorine, and an algae bloom started. had the green cloudy water. no worries, i tested and made adjustments, kept it at shock level for 24 hours. i tested the water and had it at shock level last night at 11pm. this morning the water is murky brown. ick! tested for CH, and it was still at 16. it held overnight, but the water is nastier. i will keep on keeping on, but want to make sure there's nothing im missing. we've had staining issues in the past, and wondering if the metal is back in the water, and not on my liner. does that make sense? i've got a craptastic cartridge filter, and i'll just keep letting it run, but the brown is throwing me off my game!
