Well, Im here to say that i know we've all been dazzled by numerous retailers telling us what we need to do for this and that and the other thing. Well, all i can say is, when your in a retailers shop, look around his display tanks, look for dead fish, foul odors, out of control algae, poor specimans. Then , look at what kind of equipment he uses. you can learn alot from this. Ask him what he puts in his reef tanks, and what he puts in his fish only tanks as far as supplements. Then, listen to what he has to say. I won't even shop at certain places that look poorly kept, nor take advice from the owners who just want to sell you their most expensive reef maintenance chemicals. Also talk to some of the other customers who may have reef tanks and ask about their successes and failures. Good luck, happy fish keeping.
