The Bottom Line
Electrically powered, tank rim mounted, non-submersible wavemaker which agitates the tank water surface.
Pros
- Three sizes offer more output flexibility.
- Electric powered rotator.
- Produces maximum water force from a powerhead.
Cons
- These units are not submersable.
- Mounting with hood can be difficult.
- Agitates only surface water in tank.
Description
- These units are constructed of lightweight plastic.
- Water enters the unit through a barbed fitting on the top and exits through a fitting on the bottom.
- An electric motor rotates the exit nozzle to redirect the return water in a 90 degree arc.
- Unit is tank rim mounted and can not be submerged.
Guide Review - Aquarium Currents Sea Swirl
These units require a separate powerhead or pump. The Sea Swirl has the advantage of using an electric motor to power the rotator, allowing more water power to pass through the unit, rather that being used to power the rotator. These units are tank rim mounted and can not be submerged. Using a larger powerhead will relate directly to the amount of water passing through the unit. These units agitate only the surface water and can not be adjusted to point toward the bottom of the tank. The addition of a 45 degree schedule 40 elbow would allow for water deflection toward the bottom of the tank. The unit oscillates 90 degrees (90 with the optional "Y") every 60 seconds.
