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??

45 gal custom
4 Blue rams
10 Zebras

125 gal
just fixed
Die cast cars are no good for glass aquariums
2 blue rams
2 angels
10 Rosie feeders

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.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
