I have it but don't use it anymore. I have the 12 gallon aquapod but it didn't work out in the back chamber. The light cover goes over the chambers too, and that stuffs the skimmer below the proper water level, thus it doesn't work very well back there. I moved it to the display part in the very front and it worked ok. It did a good job keeping the water clear and the quality good, but it put out microbubbles and there was always a fizz at the top of the skimmer which always made a mess. I think it might be better in a plain tank or something, but I didn't like it in my aquapod. I can't give it a bad review, but I wouldn't give it a good review either. Maybe neutral. But for as cheap as they are, it wouldn't hurt to try it out.
