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.
