Tunze 6105 thoughts

[coweyes298]

Been using this 6105 and 6040 combo for almost 2 months now. My tank is 4' x 2' x 20", with center ghost overflow. One return on the top right corner, with an overpower DC return pump with 2 random flow generator to put around 700 to 800 GPH in combine from the return.

Previously I was using a pair of Apex WAV. Since I upgrade to GHL I changed all my powerhead. Initially I was debating to get 6055/6095 at the moment, but saw some suggestion about 6105 and I pulled the trigger for 1x 6105 and 1x 6040.

I place 6040 at right back corner close to bottom, using the deflector pointing the flow to left side of the tank. It has a small form factor and it is not causing any problem hitting 100% intensity. I placed it this way to try to get rid of the detritus on back of my rock.

As for 6105 I used the narrow configuration and mount the head at back panel close to left side and about 1/3 height from the surface. I pointed it toward the front panel about 1/2 to 2/3 away from the left side. I couldn't find the ideal position using this setup. My intensity never pass 5%. This 5% already blow my sand all over the places. If I crank it more, the water will spill out. I was super upset about the powerhead and was planning to sold it and get two 6095/6055 instead.

Today I just switched to the wide configuration for 6105 and it is now on the left side panel close to back and 1/3 way down from water surface, pointing it diagonal across the long side of the tank. Much better. By using this setup I can hit the intensity to 50% and the flow is more diffused. I create a standing wave of 0.74 second period with intensity from 1% to 50%. I also changed the 1 to 10 V in ProfiLux to 3 to 8V.

Why I didn't try the wide output earlier???

Tunze is the Best!
Keep playing and you will discover many cool things with the combo you have and never underestimate the 6040

 

[coweyes298]

I may add an extra 6040 to the current setup. Right now I have my 6040 blowing the 4' direction along the back panel. It is a little bit under power. I probably need another one on the back wall close to the side blowing along the 2' side direction. I may also add another 6095 or 6105 on the right side to complete the true standing wave. Maybe..

I went with the 6150 stream 3 and 2 9040 wow better than any gyro
check it out
put vertical on the 2' wall with the 90 degree is un believable wave and under current the 9040's in the back corners bottom blowing toward center keeps my sand bed all through the tank and around rocks totally clean without blowing sand like a snow globe

6105 has great reach and flow, can reach all the way down the back of my 6’ 180.

Do you mean 6150 stream 3? Or is the combo as 6105, stream 3, 2x 6040?

I am wondering how do you place your powerhead? Any picture to share? My rock sits back and low, so my 6040 on the back corner bottom can only blow along the back wall direction. I can change them to blow the 2' side direction but haven't tried yet. I was also thinking of using the deflector to hit the back wall, but then the flow distance will be too short with no angle shown and the flow may be too chaotic after hitting the back.

What is a 9040?

 

[rvitko]

Thank you all! Yes, the wide flow is about a 5ft by 30" pattern, the narrow is 7ft by 2ft so for a shorter tank the wide flow is definitely the way to go. Typically the narrow flow is only used when the long reach and high velocity flow is needed.

 

[Dogtown]

Is it possible to order 6105's with wide flow out of the box?

By chance do you have any video showing all that flow? I'd like to see it. I need more flow in my tank and I'm trying to figure out if its possible to get great flow for SPS while keeping all the sand covering the tank bottom. It seems like an impossible task even with 3mm grain sand.

It comes with narrow and wide flow outlet which you can interchange as you wish. They put the narrow one on the body with the wide one aside. You can switch it before you put them into water.

Awesome! I was reading an old article from 2011 about switching out the 6205 covers with a 6105 pump for improved wide flow and wondered about that. Glad they are included. Appreciate it!

I used the narrow flow for several weeks and found out some of my coral starts to have their skin peeled. I aimed the narrow flow to front glass want to have a chaotic bounce of flow but I think it was just too much...

Wider setup seems more diffused and has less flow velocity. I have one acro on the path of the wide flow about 2/3 from powerhead (not directly aimed), and at the end I have a huge colony of lobo. (diagonal of 2'x4'=4.4')
I just cranked down the intensity to 35% and using a standing wave from 2% to 35% of 0.74 second for the day time. At night I switched it back to 2% steady output till the lights up. Hope this will be not too much for my coral.

don't have one yet but will get you one as quick as possible

My 6’ 135 only has 2 6105’s in a gyre configuration. The opposing 1/3 of the tank is bare bottom as a result.

 

[coweyes298]

@rvitko Hi Roger, another question. If I want to add another powerhead for my current setup (1x 6105 wide config on top left corner aiming diagonally of 4'x2', 1x 6040 at bottom right corner with deflector aiming along the 4' back wall towards left), which one do you think is appropriate?

6105?
stream 3 6150?

I have a huge sand digging wrasse so stream 3 with placement horizontally near bottom at the back wall is a nono. Thus this will also limit me on hiding the huge stream 3 behind the rock.

I've been nervous to use the wide flow attachment since there is no real guard to keep small fish from getting in. Curious on your thoughts on this.

8 year old post!
Run the wide gaurds. I run them on 2 6255's in my 150.
The smaller gaurds will create a longer reach.

Similar thoughts as to what member @X-37B noted. The open cage design will allow the flow to spread out more, width, at the cost of length. The initial pulse, water push, will be there but it will only go so far. Distance, of course, will be based on the aquascape and motor speed. Switching to the narrow attachments will narrow the cone, width, but give you that more refined, forceful, push. Length and distance at the cost of width.

I think it goes without saying that you probably already know this so I apologize for stating the obvious. To your specific question on small fish or animals. Here is my experience on my 54 x 30 x 30 mixed reef. I have a small, young, flamehawk, who is pretty precarious and loves to play Dora the Explorer. I have the wide cages installed. I originally ran the pair alternating with the speeds going down to 0, or off. Various pulse schedules alternating left, right, sides. Anyway one morning in the slower speed ranges and increased time between pulses and sides, I noticed the flamehawk resting inside of one. Picture Gertie seeing ET for the first time, that was me running from my desk to the display to shoo it out. Ironically enough the flamehawk, named Trixy btw as it already has its own story from its stay at the Fish Hotel, just looked at me as if saying chill. Before the motor kicked back on it swam away.

My point I guess is that after that incident I no longer went to 0, full stop and set it to the lower setting to always run. This prevents the fish from hanging out in or so I believe. I also have a lot of small 1/4 snails from Indo Pacific Sea Farms, Strombus maculatus, and they love to lay eggs on the bodies of power heads. Because of this I have also kept the motor running while also placing / mounting the power heads on the EURO brace so it isn't touching the display glass. So far that has worked.

TL; DR - I use them but have found I need to keep the motor running, at its lowest setting, to prevent curious fish from entering. I have a couple and found this works. I believe the ORCA's will help eliminate this problem as it will always be moving for the most part as it relates to directional which may keep them out. Some Blennies (Starry for example) and Hawkfish, seem like they are more risk takers...

Hope your day is well.

Thank you for the reply this is what I was hoping in a real world case. I have no problem running them at a high enough rate just don't want it so that fish would try taking a chance.

Also I have plenty of smaller snails and a couple small urchins I don't want to get pureed.

My tank is 4 feet so the narrow guard just isn't going to do what I need it to.
