Are my lights too close?


Recommended Posts

I have 3 Rapid Par 38's w/80 degree optics over my 20L. They are 5 inches above the water and I'm wondering if they should be higher? From reading other threads it looks like people have these Par 38's way higher than I have mine.


Any advice appreciated :D

They have them higher off the tank probably because they are using tighter optics. If your tank is reacting well to the light, why move them?
