Separating Coral Growth from Frag Racks

[BiGGiePauls33]

Anyone have any tips on removing as much coral overgrowth from frag racks with the least amount of breakage.

I had good luck disassembling the rack and bending slightly. In my case I had a frag tank with a bare bottom and simply put a short piece of RO tubing on the bottom, centered the single layer of the rack, and weighted the ends. After an hour or so the encrusted green spongode popped right off without breaking. Figure a way to bow your rack if possible, and give it time to let go, you might get lucky.
