Yeaulman Posted November 21, 2006 Report Share Posted November 21, 2006 Ok so I have a chance to get a 2 x 36W PC retrofit kit that I would like to run on 2 10g tanks. Would this be too much light or will the 2 x 13w kit that I picked up from ahsupply.com work well for my setup? Quote Link to comment Share on other sites More sharing options...
jvision Posted November 21, 2006 Report Share Posted November 21, 2006 The WPG rule of thumb is really just a guideline. I find that on smaller tanks, 4 wpg is just getting to the high end; whereas on say a 45 gal, 4 WPG is A LOT of light. If you do go with the 36W kit, you'll want to look at setting up CO2 and a fertilizing regime, for sure - it wouldn't hurt for the 13W kit, either.
