Very strong output, adjustment valve does not do anything. Maybe better for a much larger tank but not what it’s advertised for at all.

I bought this about a week ago and my betta loves it. It's calm enough where he'll swim around the whole tank Rather than before

I just bought this today!! I have gone to so many filters, but I know this will last due to how well it runs now! I actually can’t believe how good it is for the price it is.

This sucked my betta to it (I had to free him) and injured his right fin 😭 now he’s swimming with it clamped to his body and I seriously doubt he will survive. I had already turned the bubble nozzle toward the wall, because despite the control valve almost tightened the whole way, it was still way too powerful.

Perfect for my shrimp, bettas and guppies. This is definitely built for bigger tanks, I noticed a bit of splash back with the flow at the lowest setting but then I realized the entire filter needed to be submerged and this helped get rid of 98% of the splash back. I still get little bubbles like you would with carbonated soda when the water level lowers so you know when you need to fill it up more as time goes on. I love the aeration tube, it adds bubbles on top of filtering the water and even my snail will climb the filter to sit in front of the bubbles. I saw other reviews saying the flow was too strong, it does say this filter is ideal for up to 8 gallons, I use it in my 6 gallon and my 3.5 gallon with no issues, just make sure it’s fully submerged enough to not cause too much of a splash if that’s not what you’re looking for. I know some people with bigger tanks might like the water fall / ripple effect but it can be reduced to virtually no splash in smaller tanks as well. :)

Great for my 10 g planted tank. I love this filter design and wish more manufacturers would build similar products. It is versatile and I like it! We will see how long the motor and impeller stay going but I do not expect too many issues. They have replacement parts and I will be purchasing a couple more for other tank setups.

I bought this 3 months ago, it has been great! The water flow is a little strong like others have said, but not to the rediculous extent. Please note this filter is SUBMEGABLE, and is made to be fully under water. The spout should not be above the waterline, unless you want it to spray out like a hose. I have it in a 10 gallon tank even though the filter is made for up to 8gal, but it has kept everything flowing perfectly and crystal clear. This filter is a little harsh for your floating plants, but if you put a foam ring around your floaters it keeps them from being thrown underwater.

Been running for a couple weeks and seems to be doing its job. The flow is stronger than I’d expect for small tanks. I solved that initially by turning the flow nozzle around and blowing it toward the wall, but it started making gurgling noises, so I ultimately ended up taking the nozzle off entirely. Works great! Now the water just flows up like a little fountain (filter is fully submerged) and provides gentle surface agitation without blowing fish everywhere, and is surprisingly quiet.
