I think I'm using normal 17watt florescents? I have no idea, but I do know they are not plant growing bulbs. Water is changed every 2-3 weeks, and a change of about 1/4-1/3. I do not use ferts of any kind, nor use CO2.
I will post pics later. Right now the glass is covered so much you can hardly see through it. What other information should I provide?
