Review on AQQA Circulation 360°Adjustable Ultra Silence Submersible by Lorena Grant

As advertised. Easy to set up and some nice features. The front guard is removable for easier cleaning than some of the heavy duty heads. There was also a sliding screen to control the flow, which is simple and easy to use. Water circulation in each tank is paramount for food distribution and filtration. You don't need an underwater tornado, but you do need to make sure the water flow is evenly distributed throughout the tank. I would recommend this particular head for a tank up to 55 gallons. Anything larger and you'll definitely want something with a higher GPH turnover rate, but for 55 gallons or less it's ideal. I have a 36 gallon saltwater/reef bow boat and it's perfect! I also love the magnetic mount! The suction cup design of some other powerheads is just a game against the clock. Once you start getting algae growth on the sides it becomes virtually impossible for the suction cups to stay attached. Especially when it comes to solid calcareous algae. They typically last 1-3 years of constant use, so there's little reason to invest in an expensive, high-performance head when you know it'll last as long as a cheaper model. He does the same, turns the water over!
