I recently got a 45g rimless cube that is 24"x24"x18". I bought a 24" Current USA Satellite Freshwater LED (not the plus) to replace the T12 fixture that I am currently using (2x 20watts 24" using Daylight 6700K bulbs). The Current LED is so much dimmer than the T12's, so I am now using both on the tank. I am happy with the way that the tank looks and the way that the plants are starting to grow (tank has only been up for two weeks now). I just don't want multiple fixtures on the top of my tank (especially the bulky T12).
My question is, what lighting setup would work on this tank that would give me low/medium light and not make it so that I have to use multiple fixtures on the tank? I'd like to stick with the LED fixtures to stay away from having to buy bulbs every six months. Money is an issue but since I do have enough light to keep the plants happy for now, I can save up to get a really good light a month or so down the road.
Thanks in advance!
