My wife has a 55 gallon reef tank and I am worried my LFS is full of crap. We have Marineland reef capable LED lighting. Water levels are perfect as can be. The LFS rep told us we only needed to use Instant Ocean reef accelerator for the corals. See my concern here. Oh yes and we only have basic coral. Zoos, favia, mushrooms, and a yellow polyp rock. Nothing to advanced yet.
