Sump for a 125?

[Buphy]

So any recommendations for a good canister filter?

=S gee thanks guys =P think 20-30 gallons is too small of a sump?

I use a 10g wet/dry on my 125g in combination with a canister filter. The sump has a filter sock for mechanical and bio balls for bio. The canister is just for mechanical, it works great for me. I ran a similar set up on my 300g, a 40g sump for bio and a closed loop system for my mechanical.
