Removing stains from a gunite pool with ascorbic acid
I am getting ready to try this on a pool here. Are you switching to cal hypo after Ph is back up to try to get the metals to come out of solution in the filter? Raising the Cl` levels high in the filter before it makes it way back to the pool as a second way to remove the metals? Is it really worth buying the Culator if we are going to deposit the metal in the filter in this manner?
thanks
Mike
