MOVER MX4100 Rossmont USA Powerhead Water Pump Fish Tank Aquarium

Rossmont Mover MX4100
Single Pack (1 Pump)





In marine reef aquariums, waves and water movement are ESSENTIAL for the good health of the whole habitat.


Gas exchange process facilitates ingoing Oxygen and outgoing CO2 preventing alkalinity.

Coral Care:

It keeps corals cleaned of general waste and mucus excess, preventing coral’s suffocation or bacteria growth.

Food diffusion:

It prevents food deposits and lets natural nutrients to be spread in the water.


Which kind of pump works for this?

Popularly called with different names (axial pump, propeller pump, circulation pump, etc...) a stream pump (like Rossmont Mover) has a particular wide turbulent jet, gentle but efficient and suitable for this purpose.

It's action cone is designed to move the whole mass of water (as happens in nature) while common powerheads pumps in commerce are not able to solve this function because their laminar jet is too direct and concentrated.

And what about freshwater?

In the same manner, moving water supports the gas exchange with the adjcent air and it naturally facilitates the growth and the wealth of fishes and plants. It also avoids the formation of stagnant areas (dead spots) among the plants and it helps in maintaining a uniform water temperature in all its points.

Moreover, it helps the aquarium filters in waste removal.



Magnetic support of the MX series pump holds on glass/acrylic surfaces up to 19mm (3/4”). Includes special rubber components to absorb vibrations without transferring them to the environment.

3D orientable flow for maximum flexibility inside your tank.

Choose your flow with concentrator nozzle (included). Flow range between 60 and 120 degrees. Also includes fish guard grid, for safety concerns when pump is used with external timers.


Note: This pump is rated for 4100GPH, 185-210 gallon tanks. Generally, a tank requires a total movement in L/H (GPH) from 20x to 40x of its volume.
