Compact Bulb
Is a 65W compact fluorescent bulb too much light for a 20 gallon aquarium?
It’s a planted 20 gallon freshwater aquarium with no CO2 injection. I want to be able to grow plants without CO2. Thanks!
This will in part depend on what type of light this power compact emits. Generally speaking you want a 6400 K light for plants as this Kelvin temperature contains the PAR range required by plants.
Also there is a lot more that goes into the lighting equation than the old archaic rule of watts per gallon including Kelvin, nanometers, lumens per watt, and more.
I will also add that the more light you add (useable light that is) the more CO2 the plants will require for photosynthesis.
CO2 is also added by products such as Flourish Excel and by fish respiration. Make sure your tank surface is not too highly agitated so as to “drive off” your CO2 in your tank.
I would highly recommend reading these two articles for much more in depth information about this subject:

Good luck and BTW there are simple methods of adding CO2 such as Floramat kits too.
