Yet another lighting question.

[Ziggy17]

almost finished my WB 150.4 build. Here’s the lighting question. Dims 48x25x21

I have 2 Radion xr15 G5 blue on a bar. I bought these second hand for a great price. I don’t think this will be enough coverage for a mixed reef that I’d like to add more sticks to. Should I buy one more XR 15, but this time a pro, and place it in the middle or the two blu, or should I buy a XR 30 pro and it in the middle? Alternatively I have a AI Hydra 32 that I can place in the middle, which saves me from buying another light.

Thanks for the help.

Would really need to know what corals your after and a par meter to determine. I have 5 xr15 and ai blades over a 120x30x25h hi and can tell you at max with just the pros. I was maybe just pushing 200 at the top of my rock work. Though my rock does not go up more then 60% of the the height of the tank. If yours does your be able to push in the low 300 in some stops with just 2.
