Tunze Stream 3 6150

[VJV]

Hi there Roger, hope everything is going great for you and Tunze. I currently have a 80 inch long peninsula tank with the overflow in one of the short sides.

Circulation is being managed (amazingly well) by a single Maxspect gyre 150 sitting in the glass opposite to the overflow. Flow is great, but I would love to have a solution with no pumps on the viewing sides of the tank. I was thinking whether two vertically placed stream 3's, sitting on each side of the the overflow would provide enough flow for this tank. I would use the deflector to push the flow forward but was wondering if:

1- would this provide flow across the full 80 inch length of the tank? I wonder if the deflector slows down the flow

2- would such a configuration push water (and detritus) away from the overflow and keep it inside the tank?

3- would I be better with a couple of 6255 wideflow instead?

My current configuration (gyre opposite to the overflow) pushes detritus into the overflow which I find very efficient, so a bit concerned about this. However, I do see a ton of peninsula tanks with pumps sitting on the overflow wall pushing away from it and they all seem to be doing great.

Many thanks!

Here is my experience as I had a similar thought on my tank.

1) With the deflector the flow doesn't reach as far, it will reach 6ft but is very weak at that point, my home tank is a 215, 6ft long, basically a tall 180.

2) In the end I placed them on the sidewall aimed upward at about a 30 degree angle about 8" from the bottom and used the grids, the flow reaches 6ft easily, this "flow cannon" orientation was better in my case. It is aesthetically a compromise. I have an innate filtration set up of a 9012DC and 3168 filter and a closed loop to a chiller and 54W UV. I alternate the pumps at 6hr intervals and I get a nice clockwise/ counterclockwise gyre, when I feed I can see the food loop all the way around and back to the filter. The flow is definitely low on the far end, but that works for what I am doing.

3) I would definitely opt for the 6150, the 6255 is high maintenance, the 6150 has been a perfect pump, very well made, I managed to screw up and it ate gravel and it stopped itself after smoking a $4 bearing, changed it and it was back in business, the 6255 would not have survived that unscathed. The two really aren't comparable, the 6150 for its flaw of bulkiness is built like a tank and built so it can always be repaired and the motor won't die.

I should add that with the deflector, stirring up sand was a problem, even aimed up at 45 degrees I was 6" from the bottom and bounce back from the rock structure at high speed would cause the sand to just boil and that is how it got in the pump.

Thanks Roger! Very helpful indeed. However, I'm afraid that I could not live with the pumps on the side walls (would rather keep my current setup) so I guess for my 7 foot tank I need to look elsewhere.

Hi Roger, any chance of of a pic of how you have set yours up as I'm having trouble visualising your pump positioning? Thanks, Andy

 

[rvitko]

I have one on each side like this. Tank is only 4.5 months in so forgive the algae and generally very small frags.

Hi Roger. How do you think the 6150 would go using the deflector hastened to one end panel of a Reefer 250? I'm considering it as a replacement for a Vortech MP-40. Also, what do you need to hook it up to a backup battery?

For the battery back up you need the 6105.500 Safety connector, a battery and a charger, you can alternatively use lantern batteries a 12V lantern battery will run the pump for about 1.5 hours, I would use an SLA battery of about 9 Ah as this will run the pump for about 7 hours and is fairly small a .5 or 1A trickle charger is all you need to maintain it.

How big is the reefer 250? Dimensions and volume?

Oh sorry, it's 36x21x21" and 204l

Roger, above you state the 6255 is high maintenance, what do you mean by this?

The 6150 is a great pump in many ways, very quiet, and my expectation is it can probably go a year between cleaning, I have run mine now almost 5 months and I cleaned them last weekend and outside of some slime and debris, their was no calcium deposits. My calcium outside of a snow storm early on is consistently 420-430 ppm and Mg is 1280-1380, KH ranges 9-14. The high flow through the rotor chamber really works, combined with daily short backwards rotation, the self cleaning is not just a gimmick from what I am seeing. However, it is a big and a strong pump, while you could use it in your tank, I think 2 6095 is better suited. I think 2 6150 will be hard to disguise and one will not give you much ability to switch up flow patterns. I also think you will have to run them at greatly reduced speeds which will limit the flow variation you can create by pulsing.

Corey, the 6255 is maxed out for the pump size, meaning, the motor is very strong, uses 55W, for that small of a pump, this means a lot of heat focussed in the rotor well, it is not that it will heat your tank a great deal, but between the flow rate (vacuum pressure also degasses CO2) and motor heat, calcium builds up quickly, they need cleaning every 1-3 months, 2 being about the norm in a typical reef with no snowstorms and levels around what I quoted above for my tank.

Roger, I have a 48/48 cube with3/4in acrylic. With the setup I can only use pumps in the back wall which has 1/8in sheet black acrylic so it's not see through. So if I were to buy pumps, which would you recommend based on magnet strength.

Corey,

Is the back wall then 7/8"? If so the Stream 3 is completely out at this time, the strongest magnets are 3/4". I would probably use 6105's as they tend to be the most durable and lowest maintenance of the older models but I would upgrade the magnet holders to 6205.500 which is for 1".

Thanks!

Any more video review ???

American Reef has a basic overview video and Farm Boy Reef has an unboxing video. More will come soon.

I have since mid January used 2 6150 placed is hopefully vidible in picture.
Left is placed vertcally 10 cm from bottom and right 30 degrees angle forward in upper part. Both with deflectors.

I am quiet satidfird with the oversll flow, but have some small areas close to sand where the movement could have been sligthlybbetter.

Any recommendations to how to improve?

I cannot see the pumps in the photo, which is a good thing. I would try something like this. The main problem with horizontal position is when the pumps run reverse once a day to clean the intake, it can stir up sand so position them higher to solve this. Also, this photo is just one I got from Google for an example so my apologies if I stole your photo.

Sorry for unfocused picture, the pumps got more invisible than they avtually are.

Some new pictures taken from the sides of the tank..
