Question: proper care and feeding of my corals, etc

[newreefer_59]

Have had my system up and running for just over a few years now, and have learned tons along the way..sooo much to know. I have a question re: feeding my corals. I have a 150 gallon reef tank with 15 fish (tangs, damsels and chromis's mainly) with about 15 species of mixed SPS, LPS and softy corals. I was feeding them weekly on Reef Roids and/or Coral Frenzy, but recently have been using (twice weekly) a product called 'Reef snow' followed up by Kent's Phytomax and then Zoomax -- all just after lights out.

Corals appear to be doing fine, but hard to tell if this is the correct diet for them, or not. Any advice is appreciated.
