Most aquarists are well aware of the many advantages propeller powerheads have over impeller-driven pumps. Impeller pumps shoot a high velocity, narrow jet of water. A jet like this will annoy fish and it can rip the flesh off living corals… not what most aquarium owners are looking for. Propeller pumps on the other hand push a nice, wide, slower moving stream of water. This stream gives corals the massaging water spa motion they crave. This stream of water is what makes possible the many beautiful aquariums we find today.
This stream of water is the namesake for Tunze’s Stream and Nanostream lines of powerheads. Tunze was the first company to develop, produce and market pumps of this design and we’re also the company which all others try so hard to copy. Here are a few areas where we lead the pack:
- Efficiency. Tunze Stream and Nanostream pumps are, in terms of watts-to-flow, among the highest efficiency available.
- Silence. Silence is golden. While some companies charge a lot of gold for pumps that are anything but silent, ours truly are. Our pumps make no vibration noises. They make no whirring noises. They make no whining noises. They are silent.
- Low profile. While other companies use pump designs that need to stand out, in center stage on the aquarium glass, we make ours to blend in. Much smaller than the competition, its almost sad to reflect that Tune powerheads are rarely even noticed.
- Adjustability. Our patented design ball-and-socket mounting system is the industry’s most secure and most adjustable.
