I have used:
•Tetra PF-10-quiet, not much room for media
•Aquaclear 20-quiet, lots of room for media, and adjustable flow
•Eheim 2211-quiet, tons of room, adjustable, and can be used with lily pipes
•Fluval Nano filter-loud, no room for media, and easily clogged. Spray bar doesn't stay on well.
The 2211 is by far my favorite. I have it on my ADA Mini M right now.
