Just wondering am I (are we) making an error when calculating
Mine is a 55 USGal tank, 49" length, with two section 24" each
separated by a metal frame. I have two 55 watts PCF bulbs (22"), each
covering a section. Now my tank is 1 watt/gal or 2 watts/gal ??
I also have a 40 watts (48") bulb which covers entire tank. So
logically my tank is 1.7 watts/gal and not 2.7 watts/gal. Is that
