I am new to this pool thing and it occurred to me that when I backwash the filter and blow out the DE/dirt that's in the filter, it's going to just discharge on to the ground. The pool is surrounded by some rocks, so it will go there. Or I could attach a hose a drain it to the lawn I guess if that's better.
How are you supposed to deal with used DE? Is there any issue just draining it on the rocks or lawn? Is there something safer/better to do?
