Need fish to keep cycle?

[JonathanG]

Would a tank without any fish and only coral be able to sustain enough bb to keep the tank cycled?

Not unless you were adding food to the tank to sustain it.

You would have coral right? Then just feed them

If I were to have a frag tank, so a system with only corals in it, I would not be feeding anything. I would have a light that can support anything photosynthetic and leave it at that, only doing water changes to bring back essential elements like calcium. Now, if someone was to throw a wrasse in there to go after parasites it would be the only fish in the system and require pretty minimal feeding.

The question is are you turning it into a running tank with fish ect eventually?

I've been asked about putting a tank in at a business, they saw my tank at work and want something similar in their lobby. Something low maintenance.

How would you keep the BB alive?
