Xenia,anthelia, kenya tree problem.

[zum14]

Hello, been away for a bit, summer and all, well what were getting for one anyways. So as a newb my first frag was xenia, i got some kenya tree and anthelia along the way, and well now we have a problem. I said "oh ill keep up on fragging them" like anyone does and well i did, only problem is that everytime i cut, a small piece would get away, settle and start growing, and everytime i cut it down to the rock it grows back larger. Now were into plauge proportions. If i cut it, it grows, if i leave it, it grows. Between the three its spread pretty bad and ive thought about torching but that would only cause a cylce as its too much area and it would take multiple attempts im sure. Ive thought about a tank change and leaving the rock in the sump but am not ready for that. Im also thinking of selling the corals and few fish and cooking the rock for a while as im having trouble finding enough time to properly enjoy and take care of the tank. a small hiatus may rekindle the excitement. Anyone have any ideas?
