Hi masters,

Pls forgive me as I may sound stupid asking this question:

I had read thu :

"One easy and widely accepted method is to calculate the Watts Per Gallon (WPG). This is taking the actual wattage of your light tubes and dividing it by the amount of water you have in the tank in gallons."

May I ask the wattage is = to the number of tudes of light I have?

For eg, I got 2x 54w of t5 light - will make me have 108 total wattage?
