Pool isn't open yet (plugs still in, no pump, etc.). Took a peek under the cover a week ago and it was clear as a bell and cold, still with some ice. Today it is just starting to cloud up, so I'm wondering if I can hit it with something to hold off the funk until I can get the pool service to come and open. Can I hit it with liquid bleach or other treatment before the pump is circulating? Or am I just going to have to deal with whatever is there when the pump is fired up? Thanks.
