Maybe I am crazy, but I tried lowering my slab and it worked great!
When I filled in December, I added 4" in shallow end and about 12" in the deep end, but we got so much rain and sleet that in certain parts of my rink it started to overflow. Not a serious problem, but with hockey pucks at $3.50 a piece, we were losing them in the bushes left and right because we had no more boards left...
So we got a real warm spell here in Chicago. Still 3-4" of ice, but my whole slab was floating...so I punched a small hole in one of the corners and then stuck the garden hose in, started sucking on the other end, and over the course of few hrs or so, lowered the slab by about 2".
I think the key was that the water was moving out slowly AND the whole slab was floating. Anyway, just thought I would chime in to say that it can be done, and I wouldn't hesitate again to do it, if I ever ran into the same problem...but again, I think the key is that the slab was floating.
Enjoy the deep freeze!
