Culator -- Solution or Just Another "Pool Store" Product?

Marie, did you ever try increasing your calcium hardness to plaster pool levels to see if it has any impact on the staining? I know we discussed this once before and I have seen this lower the tendency to stain in several fiberglass pools that had very low calcium, including my own. I have not used ascorbic acid or seqestrant in about 3 years now since I brought my calcium up to between 350-400 ppm from the 180 ppm or thereabout I was running it at (natural water hardness when the water softener is bybassed). Before I would need to deal with the staining about twice a year. Water in the pool is still the same.
