OK,

Now that I have switched to BBB, will I have any use for the old chemicals?

Trichloro-s-Triazinetrione chlorinating pucks
Sodium dichloro-s-triazinetrione "quick shock"

I thought I had read somewhere on here that the quick shock "could" be used when I start my pool again next spring to help raise CYA if needed. But I'm not sure..

thanks in advance!!!
