So after this last shipment of corals came and a few emails later with the owner of Fraggle Reef, I was accused of basically killing my corals from acclimating them the wrong way. Here's what he said " [pre][tt][tt]Hi Fawn, Ouch, sorry to hear. Drip acclimating corals can kill them, especially highly sliming acros such as deepwaters, and double especially if you acclimate them all in the same bucket. Corals will arrive with a certain amount of die off in the bags, and drip acclimating from your tank water will spike the ammonia levels in the water and stress or kill the coral. Did they look good for a day or so and then start to fade off? That's usually a sign of ammonia poisoning in the water. All corals need is temperature acclimation to water, anything else can stress and kill them... Please keep me posted as to how they do, with good flow they may clear up. Miguel[/tt][/tt][/pre] What I did was acclimate them first to temp, ie float them in my tank for about 15 minutes in their bags. Then I drip acclimated them for a little under an hour (not all in the same bucket, btw) and placed them in the tank. I've never had a problem using this method in the past and I've certainly never heard of it being the cause of coral deaths. So now I'm curious, how do you acclimate different things to your tanks?
