Durachlor?

[woodyp]

Can someone enlighten me as to what the heck is in Durachlor 8 oz. tablets/sticks (looks like a cylinder) from Haviland? Have a friend who uses them and swears their cya never goes up. Are they combined with calcium? Downsides from their use? Thanks in advance. Yeah.........I'm tryin' to convert them!

Several different products are sold under the Durachlor name. Of the ones I could find easily, the tablets were trichlor, three of their granular products were dichlor, and the remaining granular was lithium-hypo. There may be others, I didn't do a complete search.

{EDIT} I found the sticks, they are also trichlor. {/EDIT}

Here's the msds sheets for Durachlor. The sticks are listed as Trichlor. I'd say he either is incorrect with his readings or he has a lot of water replacement.
