No but I'm going to start. I've religiously scrubbed, dipped and inspected ever coral that went into my DT but still got vermetid snails, bryopsis, and glass anemones. Not the end of the world but i'd rather not have them so I'm going to start a coral QT to protect a new system I'm building. Bryopsis even with fluconazole treatments has been a real pain so that sure would be nice to prevent with a QT.
