Frag tank.. when to move corals over.

[Amybolton2]

First time setting up a dedicated frag tank,
No sand, maybe a small fish, just frag racks in there, bio media
My question is at what point is the tank safe to add corals?
With not adding sand and rocks or a bunch of fish it wouldn’t really go through a cycle right?

if you use bio media or rock from a cycled system, there should be no new cycle to worry about. When I set up my frag tank, I took mature rock from my display and put it in the frag tank sump.

That’s what I was hoping! I was initially going to not put a fish in, but I wasn’t sure if it was beneficial to have one in there haha

I have a few fish in my frag tank, they can be "useful" for pest control (sixline wrasse, damsel) but mostly a source of bio-available nutrients for the coral. I have some trochus snails as well for algae control. check out my build thread if you're interested, mostly DIY.

If you plan on feeding the corals the tank will cycle.
