Review: I have a 60 gallon breeder, which is 4ft long, and am running co2. I have 2 Aquaclear 70's on the back, so don't have an outflow that a canister filter provides, and obviously not able to use an inline diffuser, so needed something to disperse the co2 throughout the water column. I first bought a power head that was just way too strong, so took that out within a few minutes and started searching again. Found this and it's perfect. Pushing the co2 to the other side of my tank, but not flattening or ripping out my plants in the flow. Using it with an atomizer, which is able to be tucked right beside the outflow on this. It's also very quiet, which makes it even better.
Review: I wanted a low flow filter for my fish tank which is a cubic 30x30x30 (cm). With this filter you can adjust the flow which is perfect for small fish and ideal for my betta fish. You can direct the flow in different directions with the added attachment and the filtration has been perfect for my tank, keeps it nice and clean in between water changes and when re-arranging my live plants. This filter is also very quiet which is perfect as the tank is situated in a bedroom. I would be careful when the handling of the filter, but it’s fine for me i just delicately wash the parts. Overall, impressed with this little filter.
