I don't really care what anyone says, but I am big believer in adding Vitamins/Amino Acids to the tank. I first started using Reef Plus, but then switched over to AquaVitro Fuel (also by SeaChem). I take a 1-mL syringe and squirt that amount into the tank daily.
Look up the BRS TV video by Randy that talks about adding amino acids.
I get great polyp extension and coloration on all my corals ever since doing this regimen. I don't know all the elements, but you can look it up.
I replace my carbon (albeit a very small amount) every week.
My return pump is 10x overall water volume. 2 horizontal facing 20x water-volume wave makers.
Clean water, good flow, good lighting and proper nourishment....I use the NLS Marine 1mm pellets, Coral Frenzy, grated frozen shrimp and the aforementioned "Fuel" (Aminos). In general, I like the SeaChem AquaVitro products.
