It's a nice little device for smaller tanks, but it does indeed gum up if you're not careful and you cannot take it apart to clean it.

Getting the hose clamps on tight enough to stop leaks was also a bit annoying (I really wished they went with threaded or some other type of connectors).

Lastly, be aware that it will cut down on your pump's head pressure by a noticeable amount.

Melev has a nice write up on his site about it being used as part of a closed-loop.
