Several months ago we [the Steinhart Aquarium] received a Tunze Master Stream to try out and to add water flow to one of our 4000 gallon exhibits. When it arrived we excitedly pulled it out of the box only to…
Tunze issues statement regarding the results of the propeller pump flow article
Earlier today, a water flow study was published which showed a more accurate way to measure water flow from aquarium propeller water pumps. The flow study showed some big differences between measured and advertised flow: some models measured higher than…
Propeller pump study reveals big differences between flow ratings and actual output
Now that we have some real independent data on the flow output of propeller water pumps, it is possible to compare real world performance to the rated output of several propeller pumps. In the graph above produced by Sandford, Straka…
New comprehensive flow study produces surprising data about propeller pump flow rates
A new article by Michael Sandford, William Straka and Sanjay Joshi has just produced some of the first real trustworthy independent measurements of the flowrates of propeller water pumps. The comprehensive flow study was published in Advanced Aquarist featuring the…
Sicce Voyager HP 10 pushes some serious flow with force

Stream 5000, Aquabee’s stackable, modular and directional propeller pump
The Stream 5000 by AquaBee is a late but original arrival to the reef aquarium water flow party. It has previously crossed our mind on multiple occasions that it seemed odd for such an established powerhead/water pump maker like AquaBee…
Polario 4ml, 7ml and 10ml are stubbier versions of the original
The new Polario 4ml, 7ml and 10ml are a new water pump from Rio, the company that has brought us more (blank) water pumps than you can shake a stick at. Once the dominant maker of value driven centrifugal water…
Stacking up a half a decade of Vortech drivers
The Ecosmart driver is the latest in a long line of electrical engineering projects which have continued to deliver increased performance and features to the venerable Vortech pump. The original Vortech driver was a simple metal hardware box with no…
