I'm interested in this subject. I would say that the procedure is sound, and I should be able to DIY (assuming I can be careful enough with the acid -- muriatic fumes are bad news, plus if you are down in the pool you are in a confined space and I would expect the fumes to hang around in the pool's tank or depression).

But riddle me this: before I can attempt an acid wash I have a whole lot of leaves to get out - the pool has been completely neglected for at least a couple of years before we bought the property -- will a diaphragm pump take out leaves with the water? It seems to me that one should be capable of doing so as long as we can keep the hoses open and flowing.

Please mark this URGENT! (I have received great help and wise counsel from this forum in the past, I hope you can come through again. Thanks)
