HA and Zoa Colony Help

[jonboyb]

A while back I apparently introduced a piece of LR that was infused with HA into one of my my tanks and the problem was gotten under control fairly easily. However, my zoa growout rack was near this rock and HA started on my zoas. I put them into QT in a tank with 0 bioload, just water and a canister filter running carbon, Phosban, and Purigen. However, this stuff is still going strong. Even did almost 100% PWC. Can't really scrub it like my rocks. Unfortunately....the affected colonies are not el-cheapos and I have some serious $$$ tied up in these colonies (Tub's blues, Nuclear Greens, Hornet knock-offs, Kedd Redds, etc:sad Approximately 10 colonies and LOTS of polyps each and I was growing them out to frag swap with other members.

Any advice here on getting this gone without destroying my colonies?

Predation seems like the next step. Crabs, Sea Hare etc? Maybe worth a shot....

How big she? This is just a 30 gallon tank so I don't want her to be TOO cramped. I could put the frags in the 93 I suppose and give her plenty of room to swim and forage. That would be fantastic though if you don't mind. Sending you a PM.
