Have a 55 gallon planted freshwater, 4-5 weeks into cycle, everything looking good....have 2 40watt powerglo and think I need to upgrade the lighting....any suggestions keeping in mind I don't want to spend an arm and a leg? I looked at a coralite single strip light for around $150 at LFS....is that going to be ok? Think it had 4 65 watt bulb(S) configuration it it....Help would be appreciated greatly. The salesman is willing to give me credit on my twin tube flourescent light so need to make a decision fairly quickly..by Monday. Thanks a bunch.
