Review on 🐠 AQUANEAT Submersible Water Pump 160GPH - Adjustable Power Head for Fish Tank, Hydroponics, Statuary, and Small Fountain Pump by Dawn Mattheis

Maybe I'm being a bit harsh in giving this pump a star. It really moves water and has an adjustable flow rate. It's also fairly inexpensive. I put it in an aquarium and the vibrations and noises could be heard and felt. This thing rattles, and the vibration it produces was enough for me to feel while standing on the floor next to my aquarium stand. My poor fish totally panicked. Of course I will not use this pump in my aquarium. It might work fine in an open well or something made out of concrete, but I suspect the vibration level may reduce your concrete powder. In fact, it can become a good diving toy for adults. If you plan on keeping it aquatic with something living, save your money and look elsewhere.
