Well. It's been a long time coming but the change to set up my 40b tank is now in sight.

I figured now would be as good a time as any to start this thread. This will be an upgrade tank for my 20g high nano reef.
Right now I have 30 lbs of dry rock cycling in the 40 with another 25lbs in my current tank.
This is going to be an
SPS heavy mixed reef and will hopefully have a few NPS corals as well.
I was playing around with the aquascaping today and took this pic
After the rock is cycled and the equipment arrives I will be adding an overflow and painting the back black.
I really like the hydor koralia powerheads and want two of them but am having a hard time deciding which model to get. Would anyone have some suggestions as to which would go well in this tank?
