I got a U2 about a week and a half ago. I can't believe how silent it is!!
very impressed! The only thing I have against it is that when you clean it out, it doesn't stop dirty water going back into the tank. My old filter has a nonreturn valve that stops the dirty water coming out of the filter when it's turned off. It's so much easier to clean though! And it blends into the background so much better too
there's an awful lot of space for filter sponge media too to host good bacteria. I like the fact that you can have a jet at the top of the tank with or without bubbles, or a jet at the bottom, or a finer jet stream from top to bottom. It's a shame you can only have one or the other though and not a combination. Hope this helps!
