Okay, I've heard quite a bit about how the WPG rule has become obsolete with advances in the hobby. I would like to get your opinions on my tank's lighting.
20gallon, 18" high x24" long x 12" wide tank
2x 24watt T5 HO lights
Straight up WPG is 2.8 WPG
Converted to T12 bulbs is about 3.8WPG
Lumens Sq inch is about 15.4 or 4444 Lumens out put.
What degree of lighting is this?
