I'm going to setup my first 10 gallon "serious" planted tank, for my dwarf puffers. I say "serious" because I've done low-tech before, but now I want a high light tank with CO2 and "pearling" plants. I'm using a regular 10g tank, with an incandescent hood and a DIY CO2 unit. I planned on using compact flourescent lights that can screw into an incandescent hood, but here's the question. The lights say that they are 10 watts, but are equal to 50 watts of incandescent lighting, here's the link: Compact Flourescent Light. So which should I believe? I'd be getting two, but if it's only 10 watts, that's not enough, if it's 50 watts, is that "too" much for a 10g? Thanks in advance.
