Pump recommendation Tunze

[Rixar]

Hello friends,
I'm fed up with damp, rusty parts on my Vortech pumps. I want a durable pump for my aquarium, and I think Tunze is one of the best options for me.

I want to set up an aquarium exclusively for SPS corals, so I need a good amount of random flow. I'm unsure which Tunze model would be best.

In the past, I've used AC Tunze pumps with very good results; they never broke down.

Now I've seen that there are more modern electronic options, but I don't think they'll be as durable as the older ones.

My aquarium will measure approximately 47 x 20 x 17 inches.

I've considered using two Turbelle Stream 6105 Eco units.

Thanks for your help.

Two Orca 6075s

You’ll want no sand if going with with 6105s on a 4 foot tank

I thought two 6075 units were underpowered for a 1.2-meter aquarium. I don't want the ORCA Siren; I want to mount the pumps on the glass in the traditional way.

In a dense aquarium with sand, could I use the 6105 at minimum power with the wide flow attachment? I want to have sand.

I prefer gyre style wavemakers personally, but Tunze makes great products.

2 6105's on the glass is a good option. Orca ia a better option for true random flow as you only need 2.
In my old 120 48×24×24 I ran 6 fixed powerheads, 3 6105's 1 ow-40, and 2 6095's.
In my current 150, 60×30×21 I run 2 6255's on sea sweeps and need no more.
2 6075's on sweeps is all you need. 6105's can be run at a lower speed.
I run my 6255's at less than 50% currently and have more power when the system grows in.
Old 120 and current 150 for reference.

Thank you so much for your explanation, it was a great help. I will definitely buy two units of the Tunze 6105.

DC pumps have electronics, electronics always are a limiter of lifespan, capacitors in particular have finite lives, this is why even the most heavy duty electronics in cars for example (ABS modules or transmission controllers) tend to start to be problematic after 12 or so years, eventually capacitors leak and no longer hold a charge. They will last many years, but an AC pump can theoretically last forever if it is maintained and materials used were highly durable. A DC pump, cannot. They will though generally outlast our competitors many times over and have the lowest cost of ownership as a result, but this shorter life span is the cost of control features. I would expect realistically 8-10 years from a 6105.

Off topic. When did Tunze stop making this skimmer. I just picked this up new in box. I had one years ago and not sure I will use it except as nostalic skimmer from the day. Thanks

Mid 80's I have one as well in my "museum". The main problem with these now is parts, no parts remain for the old air cooled pumps and typically they needed a rebuild (bearings) every few years. The version with water cooled pumps was made into the mid 2000's.

Cool I have seen a few used but like you said this is a museum piece like me, lol.

A bit of trivia, lost aquarium knowledge, the small wick bottle was used to apply oil to the lid, if the skimmer was foaming over like crazy, you wipe a thin bead of vegetable oil on the rim of the cup lid and then the foam pops and falls in the cup instead of blowing out the vent holes everywhere.

Its very cool to find one so complete, packaging and all. Norbert Tunze (founder) would have been running the company at that time.

I will bet there are not many of those wick bottles floating around, well at least not new anyway.

They usually got thrown out but to be honest, they got pretty nasty over time, vegetable oil does not age nicely and gets really tacky and messy. I have one, but that is the only other one I have seen.

My first all Tunze powered tank was in the 80's and had this rail mounted air cooled pump system. Best reef tank I have owned so far!

I have an Orca 6075 and Orca 6105 on my NYOS440 which is almost the same dimensiosn as yours.

The 6105 with wide attachment can not be run over 10% when it faces the glass or it blows the sand all over. At 30% it pushes water from one end to the other with no issue. The 6075 needs to be around 80% to move the water 4 feet but it runs put of steam around the 3 foot mark. When a tank is young, no problem.

I ran 2 regular 6075s on the back glass pushing water forward for a few months and it worked fine. When I ran them on the sides of the tank, I had to offset them and angle one front and one back or they would just collide mid tank
