24" high is border line, depending on what corals are to be housed and how the rock is stacked you can use the 250w, if you want sps on the bottom then 400w.

The depth is not the problem a 175 would drive that depth , But at 48 inches long then you will have to use 2 fixture and or bulbs 1 fisture for every 24 inches of tank length
