I dip everything that goes into the tank, and I am using ReVive coral cleaner by TwoLittleFishies (it smells just like Melafix so similar stuff i reckon)
I have used this on clams, frags, big colonies, live rock rubble. Call me paranoid but I didn't dip anything at all last time and had some problems with AEFW
You can see everything shoot out of the corals, mainly pods, but bristle stars, crabs, worms, it always surprises me how much living stuff can be on even the tinniest piece of coral of live rock rubble.
Im pretty bad with acclimtisation, i chuck everything into a bucket or box, then scoop in tank water by the cupful, then when i feel the ratio between my tank water and the bagwater is right, i will just add the ReViVe, let it sit for 5-10 mins and chuck all my coral/clam in the tank. Sometimes I have also been lazy and added the ReViVe straight into the bag water , dip the coral in that give it a shake and take it out and straight in the tank (when i know the coral i got it from has similar water conditions to mine), wouldnt recommend it, but its worked for me :P
