| | Re: Proper Wattage for Aquariums
I'm looking to upgrade my lighting situation for my 20 gallon tall pressurized co2 tank. I've been saving the bucks to do it. If I understand the graph up there in this thread I should purchase a fixture with two T5HO bulbs that are 24 watts. Does that mean 24 watts total or for each bulb?
Can anyone tell me which fixtures and bulbs they've purchased for their 20 gallon and the positives and negatives about them? I'd prefer to have the new fixture sit on top of the tank....just an FYI. But will definitely consider light hanging above the tank, if that's a best solution.
20 Gallon Tall
Pressurized Co2, 2-3 bps, and 1hour daily siesta
Modified HOB filtration system ( adding one more of same)
Fully planted and thriving although a bit yellow and elongated from too low light.
Root Tabs paired with swords (Just ordered Flourish Tabs instead)
Leaf Zone Fertilizer in water column
