I have a Coralife Aqualite fixture with 4 65w 6700K compact fluorescent bulbs that's acting oddly. When I turn on the two rear bulbs I get great light, but the cooling fans don't run. If I turn on the front two lights both cooling fans run, but the lights are noticably dimmer. I replaced all the bulbs about two months ago. I don't know anything about how this fixture is wired. Since it is several years old, I have considered replacing it rather than attempt repairs I am not qualified to do. If it is a simple fix I will gladly repair it. Do any of you know what would cause this problem?
I'd like some recommendations from those in the know. First, is this a repair that a guy who normally does all his own home repairs can do? Secondly, if I have to replace it what would you recommend? The T5 systems seem to be pretty economical and efficient.
Here are my specs:
. planted community tank
6 Alternanthera reineckii, roseafolia
Dwarf baby tears
small forest of sagittaria subulata
dozen or so narrow leaf chain swords
couple dozen Micro sword
