I tried to superglue the prop bar in place, didn't work to well, didn't silence it.....

I tried plain cyanoacrylate as well as a two part CA glue with no luck. I used a marine-grade epoxy, and the pump has been silent for several days now.

Per Roger, "The problem is that the tube is actually there to correct the prop rotation. If the prop spins backwards the magnet/ prop assembly flies down the tube until it breaks contact with the electromagnetic field, in falling back in it spins the right way, like a falling maple seed and syncs up with the magnet correctly. The tube is to keep the magnet from flying out of socket or hanging up on the intake screen. Contrary to popular belief the 6025 and 6045 use the same front cover."

Ahh... So I would imagine that drilling holes in the tube would be best b/c it will keep the proper rotation direction and increase the flow.

Whoops... It pays to read on before you respond.

oh well, so far it seems worth it, and i hope it stays this way. Since i didnt mess with the impellar, or motor at all i doubt this will have any really bad effects

If it doesn't work out, you can always purchase a new front cover for ~$10 (part #6025.130)

thats a good idea, i actually might grab one of those to try another pod out,

takign off the tube on the inside and outside, then somehow putting mesh covering over the front hole, make it much wider flow, and probably more flow

It is curious as to why the pump had decreased flow in the first place, unless there was something clogging the intake or something got into the shaft.

Well, I think as the name implies, these were designed for smaller tanks. We know Tunze knows how to generate flow... so maybe this is one way for them to minize it IN CASE someone actually wants one of these in their 12g nano.

I like the idea of being able to control where the nano draws water in from. right now, I get a bit of a circular flow across the top, down the other side, back across the bottom, and then up back towards the pump. If I can make it draw from the bottom even more, this would (in theory) create an exponential increase in circulation as a swirling vortex is created. Kinda like the little merry-go-round thing at the local park. You only put in a little extra effort on each push, but over time the constant additions of "energy" add up and you really get it moving.

wow, what a sweet mod. when i get my nano i will definetly be doing this

 

[mr pink floyd]

Well its been a week, and its still working fine, flows still strong, no more noise, restarts every time

 

[kappaknight]

how many times have you stopped and restarted?

 

[joeychitwood]

My noisy 6025 has once again begun rattling. I've already glued the shaft into place twice, but it keeps breaking loose. I'll try once more. Has anyone tried to heat the shaft and melt it into place?

 

[mr pink floyd]

easily 20+

the first day i did it i kept testing it, adn over a wek i tried a few thigns, it started int he air, under water, i stopped it with my finger underwater, held my hand coverign the output and it always restarted itself fine

 

[mr pink floyd]

joey, it just needs to find a sweet spot, mine will center istelf perfectly over the course of a few days and the moise will go away, it has alot to do with the mouting clip too, how it puts pressure on the sides

IMO if they made the next one with the magnets adn attatch them liek the koralia it would help alot

 

[kappaknight]

I think I'll do mine this weekend... I've had mine for about 2 weeks now and I think I noticed a slight decrease in flow... can't be sure if it's the slime building up or if I'm just imagining it. They actually look pretty good today.

I'll give it a few days to see if the noise goes away. Thanks for the idea.

its offficial ive got a ratler ill send it back to rodger when my 6055 gets in and i dont need it

 

[kappaknight]

BTW, do all of you put the rubber feets on to the magnets?

 

[GSMguy]

yes makes it much quieter

 

[E-A-G-L-E-S]

I just did the mod to one f my 6025's and it is pushing from 200-350gph more. That is about 26%-45% more flow for $0.00....
Thanks!

Finally took the 3 minutes to do this today while I was doing my water change. All I can say is wow. You can def. notice the significant difference.

Also, I think like all other powerheads, it would be a good idea to pop these out of the brackets every once in awhile and clean them as well. I noticed a lot of gunk collected in mine today while I was taking the cover off.
