I'm just starting back up in the hobby with my first non fish only reef tank. I got a nasty parasite in my last tank that I couldn't get rid of and killed my fish. I've been very worried about using live rock to cycle my new tank becuase of this. Knowing that there is Coral Rx to dip my live rock in is great new knowledge that I needed right now - also how to quaranteen it with a powerhead, heater, and bucket. Good advice.
