Review: Great compact low flow quiet filter - 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.
Review: VERY POOR - for this premium brand it is a poor filter!!!! ISSUES- suckers pull off every time you clean it and are awkward to put back in place because they foul against the inner filter trays -filter flow is very poor mainly down to the design of the pull off motor head flow escapes from the rear around the joints - inner tray is flimsy and i can not see the joints lasting long (in my opinion ) a real shame as it is a nice looking compact unit !!!!
