most of us using the stony blue type, seriously, i think the ozone may disintegrate the wooden ones faster than the blue ones. Let me do a search on the chemistry guide first..

Anyway, if u r dropping it into the sump, be careful not to let the ozone accumulate in the bioballs or ceramic rings area or all yr aerobic bac is bye bye, imho. Also, do take caution not to let ozone discharge get suck by yr return pump back into main tank... ( not my advice but from some manuafacturer's site) . use carbon after the ozone part . as a safety precaution...
