Dave,
I'm feeding a "cocktail" of Fauna Marin Seafan, Min D, and Min F; Rod's Food coral mix; RotiFeast; Cyclopeez; and Two Little Fishies Phytoplan. I'm target and broadcast feeding as much as possible during the day, mainly several times in the morning and then from the time I get home until 11:00 or midnight. Filtration is a ASM G2 skimmer, 15-gal. weekly water changes, and carbon and GFO in a BRS reactor. Carbon gets changed out every two weeks. I have been using Instant Ocean Natural Nitrate Reducer, but am starting to get a little cyano, so have cut back on that dramatically. Flow is the return from a Mag 9 and a Vortech MP40 at about half speed.
I caution anyone who is considering this that I'm feeling good about my efforts so far, but four months doesn't really count, especially when it comes to the Scleronephthya and Nephthyigorgia. Many have had their Scleros do well for about six months and then die. Nephthyigorgia are more tolerant. Dendrophyllia, Balanophyllia, and Tubastrea are relatively easy. I just stuff them full of Rod's Food Pacific Plankton every two or three days and they're happy. This is a long-term venture requiring patience and persistence. If I still have everything growing and thriving next July, I'll feel as if I'm making progress. If you want to read about people who are successful long-term, go to the RC Non-photosynthetic forum and focus on threads from Aquabac, Uhuru, and Slapshot. Those guys are setting the standard. I'm just a green rookie trying to learn the ropes.
