Im sure a few off them in your tank would not affect your tanks ph not sure how it would affect what your trying to frag on them, if you dont cure them.
I have read some people putting theirs in a mesh bag in back off toilet to cure.

I've got tricks to speeding that process up too. I make hundreds of frag discs a month
