Question about XR30W G3 pros

[Pete_the_Puma]

Hi all,


So I have recently rebooted my tank. Its a 65G 36X24X18. I am keeping mostly sps, most colonies have been in there 1-2 weeks and are doing great. I am running ULNS with Zeovit. Nitrates are at 0ppm, phopshpates are 0.09 and dropping. Everything looks great.

I initially had only one XR30W pro but could never get complete coverage on my corals/rocks because of the bracing and lid on the tank casting shadows. I have purchased and installed a second XR30W pro. (Yes overkill I know, this will all go on my not too distant 400G tank I hope, can someone talk to my wife?)

I was running my first one on a 1 week acclimatization schedule from 50% to 80% brightness output.

I am planning on running the TWO fixtures now on a 2 week acclimatization from 40% to 80% output.

My questions are: Is this too much light? not enough? just right? What would you guys recommend? I would hate to "burn" my corals.


Thanks for any advice,


Pete

It's just my opinion ( not a sps keeper), but I would use a longer acclimation period. for both fixtures.

That seems like to much light.

I plan on running two xr30's on my 65 gallon but only at like 35-40% on softies. Even sps 80% with 2 lights seems high.
The pro's pump out a lot of light and with two fixtures on a 36" tank you have total coverage so the intensity is not needed as high. imho

That seems way too high to me. I've had the first generation pros for a couple years and, generally speaking, I seem to run into trouble with burning things at about 50%. I recently changed to wide angle lenses to try to even out the lights, eliminating hot spots directly under the pucks. My lights are currently about 9 inches above the tank.

I have a 40 gallon innovative marine all in one with the xr30G3. Currently set at 25% max output. Trying to boost my par and increase growth in tank. Had it at 15% with par at 100% on sandbed just below the light. Bumped it to 20% two weeks ago and everything looks fine, just increased to 25%. Have to check par to see how everything is measuring.
