G5's on Redsea 750

[stevem650]

I have a Redsea 750. 71x24hx25w. I'm adding 3 G5 pros using the rms track and arms. With this mounting the lights will be around 9" from the water line. My question is
should I mount the G5's vertically or horizontally ? Thanks

I’m no expert. But I saw the BRStv episode on the XR30 and they used on a 120g tank 2 fixtures mounted horizontally. So I say horizontally. But on that size of tank given the width and length I would use 4 XR15 because you can distribute light better for a mixed setup. And if you want more light you could add another one and you would have plenty of light for an SPS heavy tank.
