I saw that some have done this, but I wanted some wise words on whether or not we should. We were thinking of filling our pool the rest of the way with water from our pond. We have an above ground pool that is 30 feet across. We need about 12 inches of water. If I figured right that should be around 5300 gallons of water. This is only the 2nd year we have had the pool, so I don't know too much. We wanted to take water from the pond off the end of our dock, so we wouldn't pull things from the bottom. We would use panty hose at the end going into the pool to catch anything we happen to suck up. Does this sound like it will be ok?? Would we need to shock the pool after this. I haven't checked any levels yet, but I would guess the CYA level is pretty low.
