Review on Boxtech Hang On Filter Aquarium Power Waterfall Suspension Oxygen Pump - Submersible Activated Carbon Biochemical Fish Tank Filtration Water System - Wall Mounted by Jessica Shakman

False advertising, line in the video description that the filter has an updated version where it fits a 0.67 inch aquarium rim but I have an older 0.47 inch version . I emailed the seller asking them to send me the old version but no one replied. Another issue with the filter is the adjustment knob, it's intact but removable. Basically this poses a big problem, if the handle isn't closed tight enough it has an air hole that it won't close tight enough no matter how hard I push and twist, on the verge of cracking and breaking the pipe with a lot of pressure. turn and press. The problem this adjustment knob creates is that if the filter ever loses power, whether due to a manual disconnect or power failure, suction will stop and a manual priming will be required to resume suction and flow.
