I am in the process of putting together a 40g breeder to replace my 29g planted tank. I am building a canopy for it that will have diy compact florescent lighting. My current tank is somewhat low light at about 1.2 watt per gallon with diy co2. I have been and will be growing anubias, java fern, crypt lucens and amazon swords. My question is this. How many compact florescent bulbs will I need to keep similar to slightly better plant growth in the 4og breeder. The tank will be more gallons but 2" less deep then the 29g. Would 3 sockets with the 13watt daylight cfls do?(40watt equiv) Or do i need more?
