Return Pumps: tests and real measurements compared


The last period on DaniReef.com was really full of work and ideas, too bad not only have enough arms to follow all the projects we initiate.

The project of the return pumps is now old and started with the previous article “return pumps: calculating the flow” that I invite you to read, and which proposed an excel file, downloadable, editable with most of the pumps on the market, which were often recommended as return pumps in the forums and among hobbyists. The file made possible from the data of the pumps and the prevalence of each tank, get a pump flow rate calculated for each individual pump.

Although the file would be updated by anyone, I was always curious to know how pumps would behave in reality as well as declared by individual manufacturers.

During the Zoomark of last year we decided to contact some companies in the industry to do a comparative test of the pumps.

Some have enthusiastically joined,  in true alphabetical order, Eheim, Tunze and Sicce, and they have provided the pumps subject of our comprensive test.

Tunze Turbelle Stream 6105 – The Complete Review


The Tunze Stream Turbelle 6105 can be considered as the main product of the lineup of the Tunze pumps.

These are those aquariums that are larger than a nanoreef but smaller than a 500 lt.

In this way they can still provide a decent catchment area, especially if we consider that 120cm aquariums of length are the ones which have the best ratio among quality/price/performance for keeping sps corals, which is reason why aquarist buy these pumps.

Tunze versus Vortech, what’s about the better flow?


It made quite a debate in the United States an article published in Advanced Aquarist and edited by Michael Sandford, William Straka and Sanjay Joshi, which proposes a new method to calculate the flow of the propeller pumps.

Yes, because in fact the problem has not trivial resolution. How is it possible to measure the true flow from a Stream or a Vortech?

We see therefore this and and other issues, commenting on the cited article.
