The Conch Aqua Slim is a very interesting new style of reef aquarium propeller pump. With an overall thickness that is around two inches from the glass, the Conch Aqua Slim has one of the slimmest profiles we’ve ever seen in a low pressure water pump.
The wide yet slim powerhead is possible thanks to an ‘inside-out’ motor design that we’ve seen in the as-of-yet unreleased Waveline Wavepuck, and the Polario pump. This means that instead of the rotor that typically spins the powerhead or impeller being inside the stator, the rotor surrounds the stator.
You don’t have to understand how it works to appreciate that this pump creates a very broad flow, from a housing which doesn’t project much into the aquarium, or your view of the reefscape. Of course this modern pump design is built from a controllable DC motor meaning that you can easily vary the speed of the propeller, and create very gentle yet thorough water movement, although it does restrict the angle that this pump can be directed to just 20 degrees.
At the moment there seems to be just one model of the Conch Aqua Slim, the Slim 7 which can move up to 10,000 liters per hour (2,200 gph) while using a frugal 15 watts, and is expected to cost in the neighborhood of $150. [Conch Aqua]
