Among other things, a planted aquarium needs good lighting to promote plant growth.

I have a dual strip light fixture on my 26 gallon aquarium, giving me 130 watts, which is about 7.5 watts per gallon. The fixture I have is a Satellite Compact Fluorescent Fixture Dual 24″ Dual Daylight 6,700°K/10,000°K and Dual Actinic 420nm/460nm.

This fixture has four electrical plugs. One for each dual bulb, one for the LED moonlight, and one for the cooling fan. I have my lights on a timer that also turns on the cooling fan (which is built in to the fixture). The lights are on for 8 hours a day. When the lights turn off, the LED moonlight turns on.

I need to replace both bulbs soon, but I’m wondering if I should replace the dual actinic with a second dual daylight. If I go with a second dual daylight, I can see if there’s any growth difference.  There’s a lot of talk on the forums I visit about the usefulness of actinic bulbs on a freshwater planted tank.  I’d say it’s about a 50/50 whether or not they are useful.  I think I’ll do my own tests.

My lights turn on one hour after my CO2 turns on, and turn off one hour after my CO2 turns off.

I use a total of three timer power strips for all of my equipment. I’m planning on building a “power center,” which will be made out of plywood with electric outlets built on. I’m going to have a couple outlets for non timer equipment, such as my cannister filter, power head (which I don’t have yet), and heater. I’ll also have and outlets for the timer strips. I’ll consolidate both light strips, cooling fan, and moon light onto one power strip. This will allow better use of the cabinet space under the aquarium.

That’s about it for my lighting setup. What kind of lighting do you use on your aquarium?
