I already have a prop in mind
BUT.. The magnet and motor are puny and weak as heck. I doubt we will be able to get a better propeller to spin on it -- not without trimming it way down and then you will end up with the same flow anyway. |

well this mod doesnt haev to be only done to the 6025, if the 6045-55 have stronger drives, we may be able to fit bigger magnets/props on them

Not the 6045 either. It uses the same motor as the 6025.
The 6055 is a DC powered pump and should be much more powerful. Lets see what that story is when it is released in the US. |

Yes even Tunze stated this on their forum.

I used to own the 6045 and tested them with a kill-a-watt and were measuring 1 watt less than the 6025s (although the original Tunze spec on the 6045 was calling for 8W I only got 6W). I believe that the 6025 has a stronger transformer and therefore pulls 1 extra watt and spins the magnet faster. With the mods that we've done on the 6025 it is obvious that exceeds the 6045 performance. My next post will show the modded 6025 measurements. Keep thinking on the prop idea though... I'm so interested and yes, I 'll do the flow measurements.

here is my mod i am trying on a 6025...
i was able to drill out small holes in the flange... the flow is definitely improved but not to the strength of a 6045. i like the mod without having to cut away the whole flange which may be important for prop stability.

The moment of truth...
Hey genious, hum... I meant to say jacmyoung. I made your stopper... WOW the 6025 spins right EVERY TIME!!!, so... why didn't you patent it and sell it to Tunze??? Man what a cool stopper!!! kudos to you... I 'm so impressed.
So I went ahead and modded the 6025 to the "full blast"... A deal is a deal... Mine doesn't look as nice as yours but take a look. So now the flow measurement results based on my ol bucket method again... As always I took 9 measurements and discarded the highest and lowest two, so I can be consistent with all the tests... Let's recap: The results below is the average flow in GPH 6025 without any mods: 705 6045 without any mods: 925 6025 With the mod that eliminates the inside tunnel: 1111 6025 with the mod that eliminates the inside tunnel and reduces the front plastic (wide flow), with the Jacmyoung stopper : 1078 6025 with the full blast mod and the cool stopper: 1230. Unbelievable!!! I'm changing all four of my 6025s to the full blast mod. Jacmyoung... did I have the chance to say "YOU'RE DA MAN". Good going buddy. Thanks for all your contributions and bright ideas!!! What are you going to think of for the 6055s? I can't wait...

skydancer do you still have your 6045's? If so will you also do a test with a modded 6045? I did the mod with one of my 6045's and noticed a big improvement in the out put flow. I did not however do the full blast mod... yet...
I'm just curious Dave |

Believe it or not, the more drag and friction you have on the motor, it will end up using more wattage. The stock MJ for example will pull 22 watts. Modded with a propeller it was tested at 15W.

keinreis -
Maybe you should go ask Roger. No better way to confirm on this otherwise. Then let us know what you find. |

Skydancer thanks we know we can always count on you. How about testing the full blast mod without the stopper to see how much increase? Did you check the power draw to see if there is any difference?
The flow increase from the full blast mod of course can vary based on how much is the openning cut. BTW, credit should be given to our resident young prodigy, Mr. Pink Floyd who started this whole thing. Did you say 6055? I was thinking more like modding a 6080 At 20w standard power draw who knows what that thing can do. It may blow all the bigger Tunze streams pumps out of the water and put Tunze out of business Last edited by jacmyoung; 03/07/2007 at 10:21 PM. |

Ill take credit for the original mod and partial for the wide flow mod, but the rest was jacmyoung, stop being modest, you had the tools and the abilities to make my mod 10x better.

Has anyone tested the power draw on these pre and post mod? Roger said in the other post that the 6025 has added drag.
"The 6045 is different from a 6025 in the length of this pipe, the propeller reversal mechanism and the size of the potting area over the motor coil. Other aspects are the same. The 6025 has added drag, hence the higher wattage and the lack of a reversal tab, the drag alone will reverse the propeller." I would bet that the amp draw in going down while the flow is going up. |

Octura 1435. You will probabbly need to trim it down to gte the 6025 to spin it reliably though. It is more aggressively pitched than the stock nano's prop. |

The power draw on the 6025 DID NOT CHANGE regardless of the mod. The unmodded 6025 drew 7W and so do the 6025s with the various mods... Ditto on the credits, but you my friend deserve the "STOPPER" award of the year.

I thought the stopper might have blocked some flow because you tested the 6025 with standard mod to be 1,111gph, and with wide flow and the stopper to be 1,078gph. Now to think of it they are so close they are within the margin of error under this test.
While the stopper worked perfectly for its intent, it still has the normal startup clicking noise when corrective action is needed. If put on a rapid wavemaker that can be an issue. I don't know if you noticed that. I am hoping to find a way to reduce that noise. One thing seems clear, both 6025 and 6045 probably have the same drive unit/motor since they both draw 7W, regardless what kind of flow they produce. The added drag or lack of it did not make much difference. Let's do a quick recap: We so far have done the following on our beloved 6025s: the basic mod (TBM), the wide flow mod (WFM), the full blast mod (FBM), the stopper mod (TSM), and I'd like to add one last bonus, the auto clean mode (ACM). Compared to the Tunze advertised specs, TBM has increased the 6025's flow by 68%, FBM by 86%. As put by one of the American Idol's contestants: "not too shabby" BTW I am not an AI fan but the rest of the family are. I can only hope this thing come to an end one day.

One thing I'm wondering about. Will the Stopper mod work without the wide mod implemented?
In other words can one just do the standard mod, the full blast mod and the stopper mod and have the 6025 auto-correct every time? BTW jacmyoung, you may want to edit your last post and give a different 3-letter acronym to your stopper mod as it shows the same with the standard mod.

Oops, how about the basic mod (TBM).
Yes to your other question, dhnguyen has posted a solution with pictures earlier. |

OK.. I couldn't wait till the week end so I did the test today.
I went by skydancer's specs and measured 3 gal of water out of the bucket keeping the water level even as it pumped it out. The only thing I did different was, I ran my test in saltwater (1.025 sg, I had it handy for a water change), and i did 10 test runs throwing out the highest & lowest times. I'm VERY disappointed in my findings. The 6045 slandered flow average was 850.89 GPH. The 6045 Modded flow average was 1165.67 GPH. FWIW I think you should just get a 6025 (save $30) and do the mods listed in this thread. Looks like you will get the same flow rate. I did not test the Wide flow mod as I want my stream to shoot 3 ft to the center of my tank. here's a pic of my modded 6045, I have the protective grating on the end of my housing to catch the impeller on start up. (not pictured) |

This here really makes me mad... I wasted $60 for nothing. I could have just gotten 3-6025's for the same price.
OK... OK.... HMMMMMMMMMMMMMMMM....... I'm just trying to get my blood pressure down.. I'm calm, I'm calm........ I'm just very disappointed in the results.. I think we have been deceived.. |
