I currently have a 96 watt compact fluorescent and a 30 watt standard fluorescent light strip over my 50 gallon aquarium. This equals 126 watts, which is 2.52 watts/gallon. My question is, should I upgrade my 30 watt strip to 96 watts? This would give me a new total of 192 watts and 3.84 watts/gallon. I also have pressurized co2. The only reason I am considering this change is becuase Im afraid that my combamba and anacharis are not getting enought light. The reason I believe this is because, the combamba grows but is brownish in color and the anacharis always seems to become brownish near the bottom of the stem. Any suggestions would be much appreciated.
