I have a 20x40 in ground pool. There is a leak somewhere, possibly in the lines. I had trouble keeping the water clear last year, so around August I gave up and stopped adding shock, running the filter, etc.
This spring I hired professionals to clear up the pool. They have been here every day but Sunday for over a month, adding 4-6 pounds of shock to the pool most days. They have vacuumed to waste, the pool is free of debris, and yet while the pool is blue, it is still cloudy, and you can't see the bottom.
They have tried metal removers and had it tested for phosphates, and are totally stumped. They chlorine just keeps dropping to zero, after only a day or two.
We think the leak may have something to do with it (I have to run the hose for about an hour every other day or so, mostly because we are backwashing every day), but we don't know what it would be. We just changed the sand in the filter 2 years ago.
Any help or suggestions would be greatly appreciated. Thanks.
