Review on 🐠 Adjustable Circulation Powerhead Pump with Controller - HITOP Aquarium Wavemaker Water Pump, 1050GPH、2200GPH、3500GPH by Jessica Harrison

The shaft generator is currently installed in a 40 gallon tank. I set it to the lowest value. When it's higher, my sand spreads around my aquarium and covers my live rocks. It's very strong. I recommend when installing on a long tank and not on a wide tank. Too bad I didn't buy a smaller version. But it was a replacement for another one I bought which was very weak at full power. Don't throw another company under the bus. It was for the nano tank.
