DIY question

[Iplantz]

I have a large, home built stand, and I wanted to put a 20g inside it, inline with the Dt (30g). Anyway, I wanted to make sure, a Mag 5 would do the trick for lifting the water back to the tank right? Also, with 4x24 T-5s by Finnex, what corals could I keep? Could I keep monti caps in this light? What about some LPS?

how high is it from where the pump will be sitting, up to the display tank?

here is a head loss calculator...

Well its going to be n the stand under the tank so Im thinking no more than 4-5 ft of tubing.

Thanks, my return is at 214 gph, about 11x the water volume of the tank. Is that sufficent? I will also have a powerhead on the 20g, but that is to be expected.
