    Question Calcuim Hypo Tablets

    Why is it that the only brand of Cal-Hypo tablets I can find locally is at Wal-mart in the HTH brand? I know you can get the AccuTab online, but I figured through the pool stores & or other areas, tablets would be available. I'm needing to raise my CA while lowering the CYA and thus, wanted to use Cal-Hypo for awhile. The research I recall states HTH isn't a great product, with many unwanted fillers, but I was hoping to use a tablet in the skimmer vs pouring granular everyday. Is there something horribly wrong with using their skimmer tablets vs using a quality granular product? Why is it they are the only tablets I can find easily?

    On a separate, but similar subject what is different with using the Calcium Hypochlorite made for Aerobic Septic Systems in a swimming pool? These are tablets with higher available chlorine content, although still difficult to find.

    Thanks

    Cal-hypo tablets placed in the skimmer dissolve in minutes, and often leave a sticky residue, so you might as well use powdered cal-hypo. There are various attempts to make a slow dissolving cal-hypo tablet, but none of them actually worked out.

    Thanks Jason, I knew you'd have a good reason.
