really? what type of SPS?

I would not put any SPS at the bottom in mine and I have a Pheonix 14k in 23" deep.

I put them there at the begining for acclimatation but to get them in good color they need more light or they will brown out of be dull.

So I am wondering what type of SPS you grow "colorfully" at the bottom of a 27" deep tank running low par 20k 250 watt light?

Brad's point is still true tho. I'd go with the 75 as well. It's a nicely proportioned tank. Before I went any taller in that tank size class I'd definitely go longer or wider.
