Ecotech XR15w pro and sps

VTek · Feb 16, 2017

Anyone having any luck growing out acros/millies under these lights? I have seen people have success with the XR30s but not too often with the 15s. Curious on how possible it is. Running 2 XR15w pros over 90g tank (48"x18"x24"). 75% intensity on coral lab SPS AB+ schedule with wide angle lenses. Any input from other experiences out there?

I'm running a 15 with my 2x 30s on a 65G and my growth is pretty good. I put in three to cut down on shadowing. I have it turned up @8% more than my 30s due there only being one puck. So in short, they will grow corals. Two over a 90 may be pushing it.

How much difference do you think it would make to slowly creep up the intensity to...100% over time? I'm wanting to get into the stick game and trying to think ahead.

You need to get something to look at your par. I use a luxmeter. I'm running my 15 with side angle lenses @60%, ramp up from 45% to 60% over 2 mths.
