Radion light settings

lariat8099 · Jul 1, 2017

I have a 48x18x16 rimless tank with 3 Radion pros on RMS arms. Needing help on light settings with a SPS LPS softies mix tank. Sometimes it looks to bright with the Coral Lab AB settings. ZOAS are closing. Mushrooms are thriving. Can't get a happy medium. Can anyone advise??

I run the Coral Lab AB+... curious what's your peak overall intensity?

I have a 30" deep and running G4 pros, running coral lave AB+ settings, everything seems happy i bump up intensity 5% a week and am at 65% intensity getting about 320 par 8" below the surface. Planning to go to 75%

Have you messed with flow at all? I move my stuff around until it finds a happy place. My zoas all seem to like moderate flow and whatever light they get at the bottom of the tank.

I'm at 55% intensity

Anyone else have feedback??

Your tank is kind of shallow and you have three lights so I would start around 35%. Set the acclimation timer to come up to 60% over three weeks. Pay attention to the corals and see how they do. I had a 45 gallon tank that was only 17 inches tall and eventually got up to almost 70% but it took a while. Also this link will help you estimate PAR: http://www.aquaticlog.com/radion

Start with the SPS AB+ and tweet from there. As mentioned, start off slow with these lights! Our eyes perception is allot different that what the lights are putting out. The same thing happened to me and I burnt up some nice colonies

I'm up to 67% with a 22" deep tank but it's been three months getting there

What are you using to control your lights?

Have you got access to a PAR meter?? It's really the only way to see what light you are putting into the tank. You are also in the trickier position of keeping SPS and LPS together it can be done of course but the corals requirements can be very different and lighting is only a single example of that. SPS tends to need cleaner water than LPS and the lighting spectrums for certain types of corals is very different. What where the results of your last set of water tests??
