Help, They already poured the concrete shell in my pool and now I am concerned that it is way too deep. I built a 20X40 sports pool that is 4' -5'-4'. I think that I should have done 3.6' - 4' - 3.6. Having the shallow ends at 4' feet seems way to deep for my kids to hang out and play basketball and throw the ball. It is only 4' in a small area because of the grade it keeps getting deeper until the middle is 5 ft. Should I pay to fill in the pool and make it more shallow? Is it worth it? How much do you think it would cost to change? I have four boys 13, 10, ,4 and want a sports pool. Thanks
