I have an above ground Coleman pool and use a Hayward sand filter with it. It is a 10,000 gallon pool. I have installed a skimmer in it and am using it that way with the original return that came with the pool. I am now wanting you attach and aerator attachment I bought but it does not fit and I’m not sure what the best way is to get it to work. I am trying to cool it down. I’m in south Texas and it gets hot here. Here’s some pictures to see what it looks like.
