Hey all. I'm a new pool owner and I'm trying to get a handle on our pool for this season. When we bought the house last fall, we saw what we thought was sand in the bottom. We thought nothing of it and left the pool open all winter, where a little more ''sand'' accumulated. After an algae bloom a week ago, we got the water blue, but it was still cloudy, so we cracked open the filter to find one grid was shredded, and another had a small hole along with a cracked manifold. All of that has been repaired and we're trying to clean what we now believe is DE, not sand from the bottom. Vacuuming to waste drains A LOT of water. Since there is not much else bigger we are sucking up than old DE, can we vacuum to the filter and save the water? Thanks!
