First of all, thanks helping to understand pool chemicals so I could understand my new pool last summer. My kids loved it.
In the fall, I drained about a 15" of water out of the pool, winterized it, and put the cover on. However, we've had a lot of rain (and snow-melt) this winter. The water level is now even with the the level where the cover attaches, about 2" below the top of the pool. There was ice about 4" thick on the top, but with recent mild weather, it's now about 3" thick, almost even with the top of my pool. I assume I don't want ice level with the top of the pool or it will wreck my deck and/or liner attachment groove.
I just put a hose through the ice to siphon off some water.
Is this OK with the ice on the top? I assume the ice will drop when the water leaves...
How much should I lower the water?
