How many Radion XR G6 for this tank?

Salty Sea Flowers · Feb 16, 2023

Can I please get a little advice?

How many Radion XR G6 lights would I need for a 72" x 24" x 29"; 210 gallon tank?

Depends on the type of corals you plan on keeping. I'd say 4 to 5.

more than likely, SPS and a few LPS? not really any softies, either.

You'd be fine with 4 for LPS and SPS here and there. If you go more SPS dominant you could definitely go the 5 route.

6-8 xr15

I’m lighting a 72” long, 24” wide, 25” deep tank with 4, Radion XR30’s. I will most likely pick up a 5th as corals grow or add in something in between. I would go with 4 for soft corals/LPS and probably SPS for a good long while so long as your sand or bottom is reflective.

PSA: The G5 and G6’s are utilizing the same driver and the same wattage. People seem to be of the belief that magically with new lenses and a few more blue/UV lights instead of green, they magically cover more. You can diffuse the light to cover a wider area, you can focus the light, but you really can’t magically make more PAR. The earlier Radions really did have hotspots but the G5’s have far less. This isn’t based on reviews, this is using a good PAR meter, at home, across 3-4 generations of Radions.

There are basically no more honest reviews as the online aquarium stores have consolidated and become more intertwined with equipment makers.

You can keep reading and someone will eventually suggest 3…or maybe 2…and you can run with that but @ me in 12-18 months when growth is terrible.

Having used all gen's of Radions on my 72" long 240, I would say 4 XR30's to start with, but if you get good growth you are going to want a 5th. There is also another option of using T5's or a led bar with the 4 XR30's.

nereefpat · Feb 17, 2023

Are you wanting to use XR15s or 30s?

demonclownfish · Feb 17, 2023

4 XR15's and 4-8 36" T5 retro's (if you have a canopy) - you'd be super happy with that.

X-37B · Feb 17, 2023

I run 4 xr15g5's on my 4' 80.
6 15g6's would work quite well for anything you want to grow, imo
My 80.

Go with the XR 30s for your size tank

Lavey29 · Feb 17, 2023

As others mentioned you will definitely want 30s on that size tank instead of 15s unless you go with a hybrid T5 combo and XR15s.

neonreef3d · Feb 17, 2023

I think its all according to your scaping on what model lights to get.

Definitely need the 6 on there if your going with sps. Could always do the 4 spread out and add T5 cures just about everything.

noice, noice! i think im going to roll with 5 for this build. it's always easier to have too many and be able to take one off, than to not have enough and go through the hassle of forking out MORE money and ordering (and waiting) for it. LOL!
