I always thought that sodium dichloro-s-triazinetrione had CYA in it already. Yet I have a granular form that says "sodium dichloro-s-triazinetrone-dyhydrate" that recommends adding their stabilizer/conditioner (aka CYA) to it to prolong its effectiveness.

My idea was to use that form and bleach to achieve my chlorine level and thus the bleach would be made more stable by the CYA present in the sodium dichlor.

Anybody know the answer? I really need easily soluble forms because the trichlor was bleaching my small pool's liner where the filter output was.
