3 Hydras 26hd is enough?

[wanderlei Silva]

I’m planing to change from soft coral tank to SPS or mixed reef tank.
I’m running a 125 Gallons tank 72” long with 2 orbit current USA with a loop system, and I got 3 hydras 26 HD to install, I’m planing to use the recommended BRS setting, what you guys think? 3 is enough?
Should I get the 4th one
Any other suggestion on different setting?
Please help!

Well BRS recommends 4 over a 4 foot tank for SPS so i would say no
If youre spending that much on lights, why not pick up a USB par meter? Plugs in to your computer for about $230.
