Took the cover off of my pool last Wednesday. Boy what a mess. The water was down to about 1' ~ 1.5' feet in the shallow end, floating off the bottom in a few places, and a nice shade of green. To top it off we have a Hayward filter and the bolt broke on the clamp seal/spring when I was putting it back together. I had to order a replacement kit which was pricey and am waiting for that to arrive. Hopefully the part comes tomorrow and I can get the filter running. I don't even know where to start.
I called a local diver/repair guy. He said the pool would need to be filled and clear to him to locate a leak. I filled the pool on Thursday overnight (estimated that I added just under 10,000 gallons). The liner settled, but there are some wrinkles in the bottom of the shallow end. Saturday I skimmed for about an hour and got most of the floating algae off the top.
I haven't done and water samples/tests yet, but I'm sure I'll have to add some CYA and then go from there with liquid chlorine. Hopefully it doesn't take me a month to get clear.
Filter part that broke is #8/#9 in this pic.
