One of the things I've learned from reading the forums is that wattage alone doesn't make for healthy tanks. It also involves the temperature of the bulb and how the light is distributed throughout the tank.
If you are referring to Power Compact and not Compact Florescent (which usually means spiral bulbs) then yes it will grow plants in a 10 gallon tank. The problem will actually be over lighting the tank. A 55/65 watt GE 9325k will nicely light a 20H.
Of course the above is merely my opinion and several others will comment otherwise. ;-)
I am also running a 10g and use those spiral screw in bulbs.
It is more than enough light, HOWEVER, DIY Co2 will NOT be enough.
Trust me. I've got algae all over the place from too much light and not enough Co2 and now I am have to try to salvage the tank.
I would recommend adding Flourish Excell as well as you DIY Co2. Also, you will need to increase your ferts because the plants will use them up faster with more light and Co2.
