i have a 20 L i like it alot i actually have a PC fixture on it its 2X96 watt bulbs and i have a blue liped dersa clam in there along with some sps and mainly softies. I personally would go with a 150 watt MH along with the 2 X55 .. if u went with the 25 thats 18 watts per gallon... the 150 would give you 13 and in that shallow of a tank i think youd be fine with a 150. But id try to go with a 30 long and if u do that id just go with t-5s because its 48" long... unless u wanna go with 2x150 MH with some 2 vho's?
Its a thought if i did it again id go with a 30 L..
good luck on deciding :thinking:
btw on my 20 L i have a 10 gallon sump/fuge with a modded seaclone skimmer and a mag 5 return on a sqiud. i also have 2 maxi jets hidden behind the rocks. In the fuge i have a DSB and some cheato. I have the seaclone going HOB off the fuge to save me room inside it. On a normal 20L stand from aga you have to cut the stand in the back slightly in order to get the 10 inside.
