I currently have a 29 gallon tank planted with a Coralife fixture. It has 2 T-5 bulbs, one colormax, one 6,700k. The wattage on each bulb is 18, so that gives me a whopping total of 36 watts of 29 gallons. I am looking for a little more light. Nothing to the point of needing CO2. The only think I have been able to grow well in my tank is Crypts, swords and Rotala Indica. But even those are slow, live extremely slow. Lately it's been really bad, I have tried to keep higher light plants like Alternate Reineikie, ludwigia Ovalis, I know I spelled both horrible. But the stems always die near the roots and the leaves get holey. Can someone suggest a better fixture that isn't going to need CO2. Or is there a better bulb combo to use with my current fixture. I would add though that my fish look great in the tank but I don't know how much of that is coming from the colormax bulb.
