Review on 🐠 Trupow 2115GPH Big Flow Adjustable Frequency Inline Fish Tank Fountain Aquarium Waterfall Salt Fresh Pond Submersible Filter Water Pump: Enhance Water Circulation and Filtration with Ceramic Shaft by Jenny Mendez

A malfunction may have occurred. When I first plugged it in, it started pumping as expected. Very calm, strong current, it was great! (I tested this with a large bucket of tap water) A few hours later I plugged it back in and nothing happened. I've tried several times with no success. I then took it out of the water and heard a faint high pitched noise as it was plugged in. I tapped it a few times and it started rocking. After the second dive the same thing happened - it worked a couple of times and then stopped. I will return for a more reliable pump.
