Peggy Hall.......Is "CLR Septic" ok for holding tank?
According to the MSDS, it's a "Bacterial inoculant for septic systems"...iow, enzymes. So I suspect it's just CLRs answer to RidX, which doesn't work very well in a holding tank. Enzymes rarely do because they exhaust themselves so quickly.
So it's safe enough...how effective it is in a holding tank is another matter. You have it...try it. Worst case, you'll have odor out the vent every time you flush the toilet....in which case, I suggest you try Odorlos. It DOES work.
