Just as it wondering if it is different than PVC?
I 'm sure it would be fine. I know it is safe for both hot and cold potable water. From my understanding is that CPVC is designed for a higher temperature range than PVC. The additional C in the name signifies an additional chlorine atom in the monomer.
Since the extra chlorine makes the plastic a little stiffer and melt at a higher temperature, it's probably better than PVC for reef plumbing.
