bare bottom all the way.... I started with partial sand.partial foam in a 85g I set up last year which MCC adopted..lol, but I quickly removed the sand so that I could increase the flow to keep the nuisance algae at bay. I also got annoyed with the wrasse spraying snow on all the frags.

Here's the build thread for that frag tank: (might help with some ideas)

I would definitely do a lot of things the same...this was originally set up to be a frag display tank...meaning a frag tank that was a part of the furniture in our house so it was crucial for me to do it up right.

If you can plumb into your current display more power to you...but if you cannot then it quickly becomes a complete second tank...because you need all the equipment that your main display would have.

I also like using the same lights as your other tanks so that you do not have light shock from one tank to the next and just compensate with ledges and shadowed areas for corals that need time to heal.

I'd also try to incorporate creative ways of getting more racks in the tank like racks that wrap around the glass on the sides and back wall that are held in place by a foam wall or something similar. I did something similar on the MCC 220g frag tank...but only on the overflow. I mounted racks to it.

anyways...can't wait to see what you come up with.
