Re: HTH Cal-Hypo Duration Tabs
The other company that Arch Chemical has is Poolife. Both HTH and Poolife have cal hypo tablets. HTH are the Duration ones and Poolife are the Active Cleaning Caplets, The chlorinating caplets, and the briquette shaped Active Cleaning Tablets. Have never used any of them so I can't tell you which is which. The HTH product is designed for Skimmers. The Poolife caplets are for skimmers or floaters (CLEAN, NEW ONES THAT HAVE NEVER HAD TRICHLOR TABS IN THEM!), and I don't know about the Poolife tablets.
Hope this is helpful.
Edit: The Poolife Active cheaning caplets are supposed to last for 2-5 days and if my memory serves me correctly so are the Duration Tablets. The Duration Tablets we got in this year say "New and Improved" on them so maybe they got them working right again.
