I would recomend a Precision Marine Bullet 2.
I had (still have as a spare) an Aqua C EV-240 and I thought it was great, ... until I tried a Bullet 2.
HOLY COW !!!
The difference was incredible !
The performance is night and day from the Aqua C. Don't get me wrong, the EV-240 was no dud, but the PM bullet 2 is more consistent in performance, requires less adjustments and pulls out the most nasty and smelly stuff I have ever seen. My tank is a 120G.
The down side is that it requires more muscle on the pump. I use a Pan world 150ps with my bullet.
