Tunze recommendation

I'm looking at a set of Tunze nanostream pumps. I've got a 60x18" footprint tank and was thinking 1 Tunze nanostream 6055 or 6095 in each corner for a gyre effect and to allow for reversing flow or both on for some detritus clean out. The 6055 should be around 1500gph and should reach to the end of the tank. The 6095 is ~2500 but has a much wider flow and supposed doesn't reach much more than 3 feet so I'm not sure if it can set up the gyre I'm looking for. I've got two 6045s on it now but I'm hoping for more than just on/off and one of them seems noticeably weaker than the other but that may just need a good vinegar soak or impeller replacement. Either way I'm looking for a little more kick.


I considered the vortechs but generally do not really think that's where I want to go with this tank. The likelihood of them getting bumped on the particular tank is too great.

I would go 6095. Better to have to much pump than to have to get a bigger one later on. I have a 6095 and it came with 2 front pieces one for a tight flow patter and a wide flow pattern. I would ask if they are still giving both as I got mine as they were changing to the 6095 number for the wider flow pattern, I forgot what number it was before the wide flow. They come with a couple, I would call them fuses but that's not what they do, to limit voltage 12,18, and24v you put in the power supply. I have the 6105 also they have a knob also to set flow with but the 6095 doesn't not sure why that is or if it is something they have added. Didn't both me as I already have an apex so just hooked it to that and no issues for me.


If you are having issues with yours I would ask tunze about it, they have great customer service. I got sand in mine and they were willing to fix it even though it is out of warrant cheaper than buy another new one.

The "fuses" are jumpers to select voltage. They swapped out the power supplies a while back so they're smaller and simpler now. Apparently they're also a little more resistant to splashing as well now. I'll have to pull the new 6045 and take a look at it. My older one dates back to that big brouhaha over the flow rates so they may have done a redesign on it at some point. Visually it looks the same, at least at a quick glance, but there may be internal differences.


My big concern is that the wide flow on the 6095 may prevent the clockwise/counter gyre I'm looking for and basically flow one half of the tank and the other side would be a dead spot without the second running. At which point I'd have to run both and end up with two schools of fish as they avoid the "surf zone" in the center of the tank. Plus once I pay for two 6095 units I'm in the Neptune Wav price zone but I'm reading stories of people running them at 1% to avoid sand storms which makes me think 40x turnover capacity x2 if I turn both on may be a touch excessive. :)

I would call tunze and ask about the jumpers and the extra narrow grill or call whoever you plan to order with and ask if they can open a box and tell you. I am running a 6105 on a 120 gal, 4'x2'x2' with 12v jumper and set to 40%.

Out of curiosity, how do you have your 6105 aimed?


I've posted a few other places and I'll be calling around to a few stores in the area. Maybe they have one. Out of boredom I tried just aiming the pump across the tank to center on the side pane. That seems to be working better and should get around any potential "too wide a flow" issues as long as it will make it to the other side. I'll need to keep an eye on how high I aim them and there's a visual disconnect when some stems bend one way at the top and the water flows the wrong way underneath, but I think overall this is probably going to work best. I tried putting them both on the same side and will likely try that again later tonight in that position. If that seems ok then the 6055 should work fine as I'm guess together they should be ~1500 gph or so. If it still seems weak I'll probably have to go with either the 6095 or go for the softball sized ones like the 6105. I think I'll keep the existing units in the tank when I upgrade and aim them at each other downwards towards the back and run it every so often to shove any detritus to the front of the tank and maybe run them at night for hour or so to blow off the CO2 since the flow should come up the front of the glass and flow up the front glass towards the overflow at the back.

Both on the same side work "ok". Enough motion to see, and the fish go in one direction and expend some effort to do so, but the more common detritus doesn't move much. So I'll probably want the more powerful unit to run at a sane level most of the time with the odd "flood mode" to push stuff out to where I can get at it. Plus running at slower speed should make for a more quiet experience vs. full tilt.

I have one on the back pane on the left side about 6" under the waterline pointed toward the front center pane. I get a fair amount of movement on the crypts on the right back corner on the other side of the tank. I have some rainbows in the tank and they seem to like to surf, they don't get blown away but can swim in one spot. I'm sure some people may need 2 depending on the layout. I have a island. The only time I hear mine was when I did reefs and had them pulsing at more than 75%, little louder than a clock but quieter than vortecs. If you have the apex already I would go larger than needed and dail them in with the apex. The 6105's I have came with wide and narrow grills so I hope tunze didn't quit doing this.
