General rule of thumb is 1-2 watts of fluorescent planted tank per gallon of light - five 40-watt tube is at least you tanks. If I have a tank size, I actually use a metal halide pendant. In addition, deep tank like you, only 1 watt per gallon, low growth light plants, because the light can not get a good bottom.
