I'm looking for some lighting advice for a 5.5 gallon tank. I was thinking of going with two of the 20 watt 50/50 bulbs. Is this a good amount of light? I'm just trying to keep mushrooms and zoos.
Coralife makes a nice little 2x18w PC fixture. I have used their 2x9w on my tanks less than 5g, and that has worked fine for zoos and shrooms, but the more the better
