I didn’t order this to be a filter. I needed something to create a current along the bottom of the tank to ASSIST the filter in keeping the tank clean. does exactly what I need it to do.. only reason for 4 stars instead of 5 is the adjustable output is nonexistent, or I am too dumb to figure it out, otherwise gets the job done

Quiet

Flow is for a smaller tank, is silent! Can’t say that about other filters.

I agree with what someone else said about this filter not being a good one for a Betta. The flow is much too strong and the lever on the side that is supposed to change/slow the flow, doesn't really. In the description of this filter it states that there is a "directional tube" that can be used with it, but there is not. Sadly I've been searching for a decent filter for my 5 gal. aquarium with my Betta and this is not it.

If you have long finned fish that don't do good in a strong current I wouldn't recommend this item even if you put it on the lowest setting it is still to much for

If you have long finned fish that don't do good in a strong current I wouldn't recommend this item even if you put it on the lowest setting it is still to much for my betta to handle
