I am setting up a new or fixed 72x18x24 125 gal. Kids die cast trucks and aquariums do not mix. I have built a hood with four 48" 40W bulbs, florescent. I do not have much more room for lighting. It seems very bright. To get to the 2wats/gal I would have to go to 60wat bulbs. I would like to plant a mix of swords and grasses along with a taller leafy backdrop cover. is there a bulb that is recommended for this?? Any thoughts??
Four 40W tubes is more than enough for swords (Echinodorus species); I have maintained thriving swords in 115g, 90g and 70g for more than 10 years with only two 40w bulbs plus some daylight in the room. There are a number of other good plant species that will also grow well with this much light; others will require more. At some point the light will not be the limiting factor, and CO2 and nutrients will. There has to be a balance between light, nutrients and CO2. What you want the tank to look like (in terms of the plants) will determine the balance you will need. I have never bothered with CO2 because I have achieved the look I want without it. For illustration, there is a photo of my two aquaria posted in the photo and video section. For bulbs, most people recommend full spectrum, or a mix of full spectrum and something similar. I have a 40w Life-Glo and a 40w Daylight Deluxe over my 70g, and similar (different manufacture) over the 90g.
