True, I never thought of the depth. It could be a problem. How deep is a 55? Mine is 18".jimbooo said:true but this is a 55 ie much deeper. your leaves will be much closer to the light than fishy411's
may be worth a try but be prepared to replace it if all goes brown.
Btw Jimbooo, I was looking at your pictures and you have some awsome looking tanks. Very nice.
