I did a custom CUC from reefcleaners for my BC29. I started with mature live rock from Ray, and the CUC from RC, never had my initial spike, and algae has stayed under very good control (except when I let my phosphates get out of wack). I've had the tank 2 years now. Most of the snails he recommended stayed in the sand until after dark, then they hopped on the glass and ate up the algae on the glass. Once I had the sand on the bottom bloom with some algae, and I did a refresh on my CUC through ReefCleaners, and the sand cleaned right up. I also have 2 emerald crabs, and 5 scarlet hermits.
