We have a pond in the back of our house that we and other neighbors on the pond use for the sprinkler systems. I can very easily attach a hose and fill my pool with that. I have stabilizer levels of around 150 now and trying to get them lower. Figured I could save a bunch on water by using the pond water. Since that water will be chlorinated and PHed, etc once its in the pool, would it be okay to fill it with that?
