How deep are your tanks? I have a 30 deep and am considering 3x xr30 g4 to replace 2 reefbreeder 30” modules. I like the light spread from them, but not the coral growth or color. I’m using Radiums in my other 36” deep reef and THAT color I love. Just can’t get there with the same intensity with the RB modules.
My tank is "shallow" compared to some, but it's 16" deep, with the radio about 9" above the water. I would like to raise it just a little to about 12" for a better spread. Radion's are un matched when it comes to light spectrum and par. I can't even begin to tell you the amazing growth I've seen under these lights. I personally use the Natural Deep Sea setting and have had better results with that V.S. the Coral Lab AB setting. You can't go wrong with Radions period.
