Question about cycling rock

[waynemah]

If It were me, I'd try this...

Vinegar soak, scrub off the unwanted corals, rinse, place in toilet (clean water side) to leach out the rest of the die-off, RO rinse, then into the sump for a cycle.

I'd also avoid any boiling as you never know what toxins are in your zoa/paly's.
