great thread thanks to everyone. We are not cloning humans here so lighten up..lol that seio controller sounds good i will look it up. Right now i have unmodded 6045's when i got them one of the 3 pushed alot more flow than the others i assumed i got an impeller that was not put thru the cut-down process. I have been looking for info on the bucket test i will go back in the thread and look again will test this rouge 6045. Thanks again everyone for your work.

Just did the standard mod on the 6045. Turned out my impeller is trimmed. This is what i was looking for just a little more flow and this mod took me 5min or less with no thinking or tools involved. I used a pair or pliers to stress the plastic untill it turned white a little where i wanted it to break and then started twisting at one end of the baffel and the whole thing came off slowly where it formed.(Of course i had a spare cover so i was not concerned just wanted to see what would happen if i bent instead of cut. Thanks again works great. Impellers do make alot of difference from magnet to magnet though.

Interesting. In theory, the same size and shape prop should pump out the same flow as long as the AC motor is not at or near the full capacity. The prop spinning speed is determined by the AC current frequency, in our case 60Hz gives approx. 3600 RPM. In Europe at 50Hz the prop spins at 3000 RPM.
But at full capacity when the prop is pushing the limit of the AC motor, the slipping gets worse and it reduces the pumping efficiency. The stock 6045 pump motor should have plenty of juice for the trimmed prop, so the flow should be the same even if the magnets/motors are not very consistent.

i understand so unless one is slipping then all 3 should move at the same speed. A Rep from Tunze said the device they use to cut down the impellers could be the cause but not likely. I have one impeller that no matter which pump it is in it pushes more water and another impeller that no matter which pump it is in always less flow. No visible difference. Tunze sent me a prop incase i had the "uncut" lol version. The new prop does better than the weakest one i had and i am pleased along with the standard mod on a 6045 (for now). I do have two different versions ( one has a round cord and the other is flat) this was never a problem having a flat cord, but they were just not able to get enough flat cords, after production had already begun. I think the flow is more spread out even with the standard mod, it is more even with less ridges or "veins"., just broad flow.

any recommendations on placing two modded 6025s on a 90gal softies tank? Or is it simply not enough flow?

depends on your placement, it might be enough flow including your return pump

so has anyone rated the full blast mod on a 6025 without the wide flow mod? I read the whole darn thread but only found ratings with both done. of course I mean with the basic mod as well, thats a given.

Can anyone tell me how to tell the difference between the newer model 6025 and the older? This one i have does have a metal washer that fits over the impeller shaft. I don't know how else to tell. I did the original mod, and i'm not noticing that much of a difference. Some, but perhaps because the flow is so wide i'm not able to tell that much. I dunno.
I don't know how you can break the pump while doing the mod on the screen. The mods also do not alter how the pump works so if the pump should break it will have nothing to do with the mod on the screen. Additionally, Tunze honors its warranty by replacing bad parts, not the whole pump, so I don't see why you even have to be "dishonest" to begin with.
If you mess up the screen, just buy a new one, there is no way you can claim warranty replacement of that screen even if you try to be dishonest.
I hear people justify their choice of not buying the Nanostreams by saying they just don't like to mod the pumps to void the warranty, I think they are just being lazy

Just how is this MOD done?

My experiment with my 6055 has come to an end. I had modded mine with an aquaclear magnet driver and a 6200 large prop on my 6055 motor to pump out nearly 3,000 gph. It had been working flawlessly for over two months. In the last week the pump began to vibrate.
I took it apart did not find anything wrong with the pump motor, but the end of the aquaclear magnet driver had significant wear against the 6055 stainless washer in the motor cavity, causing the driver to be very slightly off center and rubbing against the well. It appears the aquaclear driver was not made for such wear and tear.
I have since put the stock 6055 prop unit back in and it is running silent again. At least the experiment proved how powerful this little 6055 DC motor is, if only there is an off market magnet driver that can withstand the high force pressed against the washer.
With the 3,000 gph 6055 out of question, I will likely go with plan B, which is two 6045s modded with 6055 props and run on a Seio controller. The variable flow will be similar to two stock 6055s on a single Tunze controller, each pump pulsing from 700 gph to 1,500 gph at the same time.
