I was thinking of starting up a 20g long planted tank.
If i get the 20g long, and purchase the Coralife 30" T5NOs 2x18w, would 1.8wpg (36w/20g) on a 20g long be enough light to get any plants I want or would I want to look at the 3.5wpg range?
And at what wpg would pressurized CO2 be suggested/needed?
