miniwhinny Posted January 31, 2011 Share Posted January 31, 2011 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 Link to comment
evilc66 Posted January 31, 2011 Share Posted January 31, 2011 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? Link to comment
