I don't think the CAMEO site is going to help you much. The entry in CAMEO you are seeing is for SODIUM DICHLORO-S-TRIAZINETRIONE and SODIUM DICHLORO-S-TRIAZINETRIONE DIHYDRATE with greater than 39% available chlorine.

I found the MSDS for the product you mentioned "ClearView shimmer n shock" on the manufacturer's website and it indicates (may be out of date) that it is undiluted dichlor. It is fine to use in your pool to chlorinate and add CYA.

I'm guilty again of "simul-post"
