Cal hypo tablets...

[PoolDoc]

Cal hypo tablets have been around, but are rarely available. Best check the ingredient list CAREFULLY, however.

As far as lasting, when you're away from the pool, I haven't tested, but I'd guess trichlor tabs would last longer.

There are two types of Cal- hypo tabs: encased and solid. The encased ones are in plastic tube with holes in it. I've never had a chance to use them but I did have the others once. They were dreadful, turning to mush and clogging my skimmer in about a day. If you do use a floater, do NOT use one that has had Tri-chlor in it. Potentially dangerous. Buy a new one because they are usually cheap enough, around $10.
