Thanks Defdac, I really appreciate the offer. My tank is a 55gallon with approximately 10 gallons displaced by substrate and biomass. Substrate is 100% fluorite. 95% coverage with microsword, the rest of the plants are anacharis, pond penny, red sword, anthera and some rotala. I run two banks of light 130watts each for total of 260watts of power compact fluorescent. Lights run together for 10.5 hours a day with one bank coming on and going off 1.5 hour before and after the other bank for total photo period of 13.5 hours. The reflector in the light hood appears to be a high polish stainless or aluminum. I do not know exactly but it came with the light hood. I dose trace and macros daily througout the week for total of 2.25 tsp KNO3, 1/2 tsp KH2PO4, 30ml Flourish, 20ml Seachem Iron. I do 50%-70% water change every Sunday without fail. I have been on the verge of switching over to T5 lighting for quite some time now because the color spectrum I want is not available in the power compact fluorescents. But I have been trying to hold off until I get the plants growing right. But if switching to T5 is what I need to do to get things running nice and smooth I'll do it today. Thanks again....
