|   Did anyone think this D120 is not bright enough?  I run both channels at 100% and still my 4 x 39watt T5 is brighter.  My tank is 3ft x 2ft x 2ft tall.  I run 1 D120 about 8 inches above the water.  The light doesn't penetrate deep enough.  Does anyone in lower mainland have any of this I can take a look or compare?  Maybe mine is defective Last edited by milou; 05-08-2013 at 06:03 AM. Reason: non |
