I mistakenly purchased some (what I thought was 99% - didn't read the label close enough) Trichlor tabs that are 94% Trichlor and 6% "other ingredients" (84% chlorine). Kind of concerned about the other 5 or so percent. The brand name escapes me, but I can get it if needed.

Should I just toss these and get the 99%? I use tabs until my CYA is in a good range.
