Radion G4 Brightness, Share your success!

Wankell · Oct 10, 2017

Hey guys and gals,

I'm getting back into the swing of things after about a year of having a running yet empty tank and over the past week I have found it a little difficult to gauge the brightness of what to set my XR30 G4 Pro at. I have browsed Youtube, Multiple forums, Google, etc. in search of examples but haven't found a whole lot of data.

I was hoping people could pitch in their profile settings, specifically for the G4.

I understand that it will vary due to different types of coral being grown, and yes I know Sanjay runs his G4's at 100%, but the options are limited, so I am hoping this can be a resource for anyone else looking for this type of information presently or in the future.

____________________________

Right now I have an XR30 G4 Pro on a RMS mount over a shallow tank (IM Nuvo 20) and have the overall brightness set to 35% running the AB+ profile with a slightly longer ramp up and down. It has a single zoa and a recovering micro blasto colony, so the corals are limited, but eventually I want to run mixed, including SPS. I am curious to see how others are using this new gen and how much power is being thrown at your reef.

I based my schedule off of a video I found on youtube by ReefDudes here, in the video they are G3's but since then he has upgraded to G4's.

There are quite a few G4 users around. I'll bump this in hopes some of them might respond.

Thanks! The information is out there but it's so spread out and a lot of digging has to be done, figured it might be beneficial to try and collect data here, but perhaps it was a bad idea. ;Meh

Hopefully someone will chime in. I know @d2mini has G4's. Not sure if they're pros or not.

My G4 Pros are hanging 17" off the water's surface, running the AB+ program.
My lights are set to around 70-75% overall brightness with PAR in the 250-ish range about midway in the tank.

See par chart below.
The blue numbers represent par on the sand bed right at the front glass, whereas the rest of the measurements were taken as close to the center of the tank as possible.
(Also, ignore the wide angle lens distortion making it look like the radions are not spread evenly all the way across the tank. They are.)
