Just to point out, the 3% will work, but it's too weak for long term 
use to regenerate.

Well, that may be true, but from my experiance it isn't. From my 
experiance the sure way to generate lots of chlorine is to put in too 
much H2O2. The extra oxygen bonds with the hydrogen in the HCL to 
make water and in the proccess it frees pleanty of chlorine.

Since I don't use H2O2 to regenerate, I haven't seen this issue since 
I mixed it up to start with.
