Hey noob, managing an lfs for a year and talking to coral wholesalers on a weekly basis you learn a few things. Most corals that come into their facilitys usually are boxed up and shipped out within hours of them receiving them, meaning they don't have the ability or time to "clean" said corals. AEFW , zoa eating nudis , sundail snails, just to name a few, get passed on to your lfs. Now im not saying that this happens on every shipment, but it happens more often then not. So dipping your coral to me is probably the most important thing regarding this hobby. I use and recommend a triple dip method. At the shop and at home i use revive , coral rx, and lugals solution(for eggs). Sorry so long winded , but one time not taking precautions can wipe out an entire colony. I hope this helps. Because its not just the cost of coral, but the one you lose could be your favorite coral. And that sucks!
