I have been messing with this pool every day this summer, my kids have only been in it 3 times. It’s always cloudy. I put in a bag of floc yesterday and the whole bottom of pool was brown like this. I have intex vac that just sucks it up and blows it back into pool. I have that super cheap vac that you hook the hose too and same thing. Saw YouTube videos where people attach microfiber mitt inside out, doesn’t work. Only thing that got rid of it was siphoning it out with hose. Got in pool fully clothed last night and very slowly sucked it up and it was all out. Pool looked great. I then added bag of shock and turned on pump and went to bed. This morning it’s awful again. I only have test strips, can’t afford $100 kit at the moment. My chlorine is showing very high. Stabilizer ok. PH and alkalinity normal range. Intex 5,000 gallon pool with upgraded pump.
