we just filled our 15 x 42 intex pool, which we’ve had for 3yrs., and put shock in, we have a super filter w/ 3/4 hp motor, to ensure good water.(the filters that come w/the pools aren’t big enough for a fish tank!!LOL)The water is now a "reddish" color…….this has never happened before. What do you think happened?


Red coloration probably indicates metals, most likely iron. You can add a metal remover chemical and that should take care of the problem. This tends to happen more often with low water levels like we are seeing now with drought conditions in many parts of the country. It may also be from rusting parts, but in your case there is little metal to rust, so more likely the source water.
