Review on 🐟 Enhance Your Fish Pond Air Pump with FarBoat's 10Pcs Aquarium Diaphragm Silicone Cup Replacements by Matt Maxwell

This diaphragm has the correct ID and OD but is 2mm larger than the original parts. The bezel also doesn't have a notch on the inner diameter, which is meant to match the look of the white plastic camera that holds it in place. I tried removing the extra nut to make up for the 2mm height difference, but that still left the magnet in the wrong position for maximum pumping action. The video shows the original screen on the left and this element on the right. While it fits, it doesn't pump as much air or pressure as the original Tetra Whisper 60/100 cone.
