What would be the better option on a 125 gallon?

6 bulb tek light or the 8 bulb? Is there any need for the 8 other than a little more par?

Depends how wide your 125 is. If it was 18" I'd get a 6 and over that an 8. It wouldn't be so much higher par numbers as a greater area covered with high amounts of light imo.

The tank is 72" by 18" wide by... 22ish? tall.

I dont' care about the ends of the tank, they can have less light.

At 18" the 6 bulb is good enough. I have a 20" wide tank with a 5 bulb aquactinic and I wish I would've gone with a 6 bulb system. The 8 bulb isn't necessary, but if you're planning to upgrade to a wider tank in the near future go for the bigger system.

Thanks all. The 6 should suffice then.
