We have a problem with the indoor pools we deal with. Many develop a white hard residue. We have tried just about every chemical you can imagine. I don't think it is calcium, but dried up residue from the pool water which could entail the chemicals, oils, etc. Any ideas on a chemical that could safely remove the hardness? We have tried hydrochloric, bleach, phosphoric, tile cleaners, etc.
