I got some bleach that said regular splashless. I was told I can use it for rock curing so I did and someone else told me it's a no no. It did foam up and my question is can I save the rock or just throw it away?
Rock is too expensive to throw away. Probably just needs a soak in some RODI outside for a couple days, then rinse and soak again. If you can, let it dry out in the sun.
