Review on 🐙 Coral Vue Technology AC20290 Octopus 8-Inch Needle Wheel Skimmer: Ideal for 250-Gallon Aquarium Filter by Michelle Davis

I like the product, it works exactly 1 week and shoots on the first day. The reason for the 4 stars is that the pump makes a distinct humming noise when sucking in air. When the air intake is closed it's completely silent, so I assume it's a vibration issue as the air enters the impeller. Aquatrans 3000 needs to be reworked or somehow gently separated from the body to dampen vibrations. Apart from the background noise, a very pleasant product.
