My boyfriend and I are buying a foreclosed home that has a large in ground concrete pool. The pool is in good condition, but is somewhat of a frog pond at the moment. We plan on draining it and cleaning it, then filling it. Neither of us know how to care for a pool though. A friend told us that salt water pools are less maintenance, but is it safe for concrete? How expensive is it to care for, chlorine or salt water? And how much does a custom cover cost? Because the shape of the pool is definitely unique. Thanks for helping out!
