PoolDoc:
This is my second year of having to do the ascorbic acid treatment. Works like a charm. I stayed stain free until late August last year--Im sure its my well water doing me in.

My question is-can I use the calcium hypochlorite tabs with my DE filter? I'd like to try and get the iron out of the water. I do use the Culator pack in the skimmer.

Thanks for your time.

Use the methods above, but order these:
CCH Calcium Hypochlorite Tablets 50 lb bucket

You can use cal hypo tabs like these in the skimmer -- ONLY in the skimmer -- to remove iron and place it on the calcium residue from the cal hypo, which is then trapped by the filter.

Chemically, what's happening when you use these correctly is pretty complicated, but practically speaking, it's very, very simple. Let me know when you have them, and I'll walk you through it.
