That after 2 weeks, it doesn't work really. It seemed to work well at first. Now, the flow is terrible, sometimes nonexistent, even after cleaning. I think I may return it. But, the reviews of the other small filters aren't much better, so I'm not sure what to do.

Filter pops off suction cups. The suction of the filter itself isn't very good. The only good thing about this filter is being able to adjust the depth compared to water line.

I had this in a 2 or 3 gallon betta tank, later used for a pair of glofish danios. It would constantly (weekly) get clogged up and stop working, requiring me to take the entire unit apart and clean it. The tubing is not easy to put together and comes off very easily where it connects to the filter inside the tank. It's just entirely too much trouble.

It is a nice filter but as all know Betta fish likes the water to be calm well I figure out a way with this filter. Soo, how I rigged it is, I took a 16.9 fl oz water bottle cut off the bottle and the top , then cut abt an inch slit up the side not all now all the way to the top so it won't slip when you wrap it around the black part of the filter and also the air tube.
