With EHEIM streamON+ you have more flexibility than with any other propeller pumps.

Eheim`s new streamON+ streaming pumps are suitable for use in both marine and in fresh water aquariums. They are small, highly efficient and energy saving. You can position them vertically or horizontally and turn them up to 180°. This allows you to turn them in any direction (3D function).

The stream ON+ has a more-convenient magnet bracket that is easier to align against the glass. Also the outflow can be smoothly adjusted in small increments.

Eheim from Marine Depot

I rec'd the Eheim circulation pump quickly from Marine Depot. My experience with Eheim goes back to 1975 when I purchased my first Eheim product, a canister filter, which stills works after 40 years! Equally significant is that parts are still available for this model. Bottom line: The Eheim circulation pump works great and Marine Depot has been my favorite place to purchase from since my first purchase from them back in 2002. Bill

Good powerhead

Overall, it seems to be a good powerhead and it's not overly expensive either. I bought it to complement a gyre 150 in my new tank. Easy to adjust, take apart, and it's very quiet. It's also not as bulky looking in the tank as some other powerheads. Being an Eheim product, I imagine the durability will be on par with their pumps, which are excellent.
