I hope I am not posting this in the wrong place!
I have an above-ground pool which I am converting from Baquacil to chlorine. I bought the house last year and so I'm also new to running a pool. This site has been super-helpful for me, but I do have a question I can't find an answer to.
I have followed the conversion steps and I'm testing the overnight chlorine loss and hope to be able to change the sand in my filter soon. I'm looking forward to this because 1) I don't know how old or gross that sand is; 2) ants seem to be living in the sand; and 3) it means I can soon use the pool!
However, I am worried about keeping the water in the pool while I change out the sand. I have a plug for the skimmer which should prevent that from draining, but what about the return? Should I have a plug for that as well? Is such a thing available, or should I just use the cork from a wine bottle (my dad's suggestion). I have put a lot of water into that pool and I would prefer that it stays there!
