Regular Member amynmitchell Posted July 27, 2010 Regular Member Share Posted July 27, 2010 With my new 40 gallon tank I got a 24 inch plain florescent hood. I haven't used it because I have been using my 20 inch T-5. The bulbs are dimming dramatically in the T-5. I do have some dark spots in the corner of the the tank as it only stays light in the middle. The 24 inch still isn't quite long enough, but would reduce the dark areas, but would be less strong light. So, the question is do I get a bulb for the flourescent or replace the T-5 bulb? I wanted to run them both, but they don't fit on the tank together. The plants are starting to look a bit sad. Lots of brown algae and yellow spots. 0 Quote Link to comment Share on other sites More sharing options...
