The tank has not been set up yet which is why i was asking.
The tank is 1220mm Long X 460mm High X 460mm Deep. I have quite a few plants to put in there from my growout tank. And in the tank are two large angels, two large severums, one suranimensis, 2 plecs, 2 BNs, algae eater, moonlight and snakeskin gourami, (and yes i know most people wouldnt recomend the mixture but....)one electric yellow.
And my next question is, i have two places for light bulbs, will 20W each light be enough or two much?
