I currently have 2 XR-15 Radion Blues (G6) over my tank (IM 75INT). I'm getting good PAR readings but aesthetically, the tank is just too blue for my liking. I have them set to AB+ which has all channels 100%. Whenever I dial back the blue settings, the PAR crashes so I don't want to tune them back. I'm toying with the idea of adding a 3rd light tuned to the white spectrum purely for aesthetic purposes. Since this is a luxury and not a need, I'm looking for an inexpensive option. Any ideas?
