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. This is because they can be used in aquariums from 300 to 400 liters, which are the ones most advanced aquarist chose to use today. 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.

The cost increase of neodymium, Tunze reduces the magnetic holder


As mentioned in the article in August, the cost increase of neodymium has a negative impact on aquarium.
Nevertheless Tunze freezes the prices reducing the magnetic holder.


TURBELLE STREAM 6125 — had a “magnetic holder” up to 0.98 inches, now reduced for thick glasses up to 0.59 inches.
For example, the pumps 6025-6045-6055-6105 were provided with a magnet that held a thickness up to 0.75 inches;
in most cases the magnet was oversized, so Tunze adapts the pumps according to their use, as follows:

6025-6045 had a magnet for glass tickness 0.75 inches; now it’s reduced with one up to 0.47 inches;
6055-6105 had a magnet for 0.75 inches; now it’s reduced with one up to 0.59 inches.

However, if the customer had special needs, he could buy the suitable magnet holder separately.

Tunze Stream 6105, Recensione


Le Tunze Stream 6105 possono essere considerate come il prodotto di punta delle pompe Tunze, nel senso che sono indicate per quegli acquari fra 300 e 400 litri che probabilmente sono quelli più utilizzati dagli acquariofili cosiddetti evoluti. Cioè quelli che hanno un acquario più grande di un nanoreef ma, purtroppo, più piccolo dei 500 e più litri che si possono trovare in giro.

Quindi hanno ancora a disposizione un discreto bacino di utenza soprattutto in considerazione del fatto che gli acquari da 120 cm di lunghezza sono quelli che probabilmente hanno il miglior rapporto qualità-prezzo-prestazioni per mantenere i coralli duri sps, primo target di queste pompe.

Aumenta il costo del neodimio, Tunze riduce la portata dei magneti


Come anticipato nell’articolo di Agosto sull’aumento dei costi del neodimio, iniziano ad arrivare le prime conseguenze negative anche in campo acquariofilo.
Avevamo predetto un aumento dei costi dei magneti, ma Tunze ha optato per una riduzione della loro portata di modo da contenerne i costi.

Turbelle Stream 6125 montava un magnet holder fino a 25mm ora ridotto per vetri spessi fino a 15 mm.

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.
