2x13 watt bulbs or 2x18
well, im finishing up a little ten gallon tank and im wondering if a 2x13 (cf) or 2x18 would be a better amount of light?
What do you think?
2.6 watts per gallon or 3.6. i guess the watts per gallon is kind of frowned upon anymore but it does give you an idea about the intensity of the light the bulbs are gonna put out in that sized tank circumstances.
Which do you recommend?
