I have a 2ft one of those, 3x24w, couldn't be happier with it. But I reckon you'd be able to fit extra lighting to your existing hood. Are you able to take photo of the underside of the hood? There is always a way to get more light under the hood. Some people just rest the light on the central glass brace!
Sam
My hood is the standard Fluval Hood, with one light in the front section, then a huge tray coming down which houses 'a few' wires and the starter unit (This is far too big for what it holds) then a light in between this tray and the back (The very front is a hinged flap, which I use when feeding etc. basic Side view below. There is no ledge to put a glass tray on. Just an open tank and the black plastic hood that slides onto the top.

Basic pic I know but gives the jist. If I bought this unit from ebay, I could probably cut the correct size from the current plastic hood, and fix the luminaire unit into the space rather than have it above the tank. I don't want any of the surface to be open.
alternatively. Looking at it and getting my thinking head on, I could get 2 twin starters, cut out the plastic tray and then fix 2 more tubes where the tray was, giving me 4 x 18W (staggering them so that 1 and 3 reach the left of the tank and 2 and 4 reach the right of the tank)
What do you think? Am I making too much work for myself. I'm sure you can see what I mean about the original hood. It just keeps things tidy and keeps the tank safe from any airborne pollutants, like furniture polish etc.
Sam I've been reading through your low light journal seeing as it is a similar size tank (mine is 30L x 15D x 18H). I notice that you had 26W over it. so about the same as mine with 36W (1.24WPG even if it was full to the top, it's filled to 1 inch from top)
Your tank looks a lot brighter than mine! Is that just because you have a good camera, or am I doing something wrong light wise?
Very interested in any plants that you think I could add to mine that don't mind low light. (see list I currently have on page 1)
Like yours I am heavily overstocked without any 'respiratory' problems I have roughly 35 inches in there, maybe more.
My problem is that I bought a collection of plants, which I think is the best value when youre a noobie, rather than wasting money on indiviual plants only to have them die. There seem to be a few that want high light and are deteriating quite rapidly, so I want to replace these. I want some red or reddish plants that will stay red and still grow under my low light, any ideas?
