4FT light on a 5Ft tank?

[BCOrchidGuy]

I think a 60 x 24 x 20H tank will be almost perfect I may go for a 22 High. The 20-22 inch height will give me lots of room to work vertically but the 24 inches front to back will give me more show (fish) room. The height will also mean no need to upgrade the lights as they are pretty repsectable on the 24 inch height.

20 inch Height makes it a 125 gallon

22 inch Height makes it a 137 gallon

Just for sake of thinking out loud, if I went with the 22 inch height and a 30 inch front to back, ..... 172 gallon..... hmmmmmmm
