Greetings! I'm wondering about what's up with my pool, and if I might have a leak in one of my return lines or some thing. Since opening the pool, it seems that after a couple days I'm continually getting this gritty, sandy type debris that builds up at the bottom of my pool. It clings to seams and corners, of course. At first I thought it might have been dead algae from opening or something to do with all the rain we've been getting, so I've just been vacuuming it to "waste" once a week or so. It's still going on, so I'm starting to get concerned. Are one of my return lines busted and taking in a bit of dirt? I don't seem to be losing a crazy amount of water ... maybe an inch a week with full sunlight from dawn to dusk ... seems normal, doesn't it? Or, is it possible that it has something to do with my changing the sand in my filter this spring? I was careful not to damage any of the fingers when I was vacuuming the old sand out, but maybe I did something by accident.
Any help or insight would be much apprecaited! Thanks in advance!
