Review on 🐠 hygger Double Head Aquarium Circulation Pump: 2100GPH Wave Maker for 110~240 Gal Tank - Silent Operation, Magnetic Suction Base by Christine Cepeda

I needed another circulation pump for my 90 gallon cubic tank. I was concerned it would create ripples and I have a rimless aquarium. The good news is that this is a simple two-head circulator. The heads do not move individually, but in tandem. You can tilt and rotate it as you like. It has a suction cup with a magnet. The weakest point is the connection of the pumps to the main base. It's like a conical pin that you push in, but there's no "lock". I am afraid that over time it may vibrate and fall into the aquarium. However, so far so good. It's not too strong for my 30 x 30 x 29 inch cube. Perfect water flow for this 5W pump.
