    Radion XR30W Gen 3 Recommendations?

    I've just acquired four Gen 3 XR30Ws and am (FINALLY) setting up a 150 (48L x 24W x 30H) that I've had collecting dust in the dining room. Is anybody using them over an SPS tank? If so, can you make recommendations as to how many you're using per square foot, height above the tank, spectrum and intensity?

    Eco techs specs cover a 2' x 2' x 2' section of your tank at 9" above the water. Attached are my specs with amazing growth and color for LEDs. After comparing the radions to my halides, I think that the radions provide (roughly) 80 % growth and 80 % color that halides do. Pretty awesome considering you don't have to change the bulbs every 6 months.

    I run my lights 2 x a day instead of one 8 hour long daily routine.

    Interesting. Why did you choose the double lighting pattern?

    Double the photosynthesis time. My corals get two days for every one day I do. I also get to view my corals before work and after.

    That's awesome! Never thought of running lights twice in one day... I assume you don't have much/any natural or room light during your mid day rest?

    Dana Riddle goes into detail on a dual day cycle in his macna 17 presentation. He has had good results using it.

    Thanks. I'll have to bend his ear on that, although I could only find his presentation on alkalinity and water flow vs. photosynthesis from 2016.

    Maybe it wasn't macna 17. I'll have to look thru my library and find it for you.

    Dana said he hasn't looked at that kind of dual photoperiod, but I did see in his 2016 MACNA presentation that he said photosynthesis in a shallow tidepool happens twice per day because of photoinhibition mid-day. That's not the same as saying that you should light your tank twice a day though.

    There's, apparently, a video by Mike Paletta in which he claims Dana said that.

    It's interesting what he did observe, though. He's suggesting that PAR should be limited to 200,at least for the porites he tested, but I've had acros that didn't do well until I hit close to double that.

    You may be right. It was that video that gave me the idea to do it. We have been doing it for at least 6 months now. It did make a positive difference.

    Can you find the video link. I've looked and can't find it.
    Don't look here for a comment.

    Until I get the 150 up and running, I've set up the Radions, Apex and WXM module with my existing 110G. I'm using the "coral lab" project settings for the Radions. Essentially, it's a 12-hour photoperiod with the blue, royal blue and UVs at 100%, and red, green and white at 24%. The total intensity for each Radion is limited to 40% of max wattage. The Radions have been running for a week, and I'm trying not to convince myself that the corals are already looking happier.

    I can't say whether I really like the Apex yet. The temperature and pH probes are dead on, from what I can tell, but the salinity probe is a PITA to calibrate. I had to order additional calibration fluid because the packet it came with got used up. The probe is reading 33 ppt (1.024+), when my two other hydrometers are saying 28 (1.021). I've read that I may have to shut off the rest of the motors/lights to eliminate possible interference.
