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

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

yes makes it much quieter

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.

yea, cleaning it does help with the sleek look, i get flakes stuck on it all the time

im glad this mod helped people out :)

50g with two 6025s and a seio 620 and i am starved for flow but i would rather keep my warranty

Simple, yet effective. :) Well done sir.

I modded my 6025 over a week ago. It resulted in a noticable increase in flow. All seems fine with it.

I had a 6045 on reserve with the LFS, they said it was in and I told them I didn't need it at this point.

[B]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[/B][/QUOTE] That is exactly what has happened. My pumps are completely silent now after simply waiting a few days.

I performed the mod weeks ago and have had no problems with starting properly. The increased flow is trmendous. I would not want more at this point. And, as always with Tunze products, Roger Vitko's customer service is superb.

I also modded mine a few weeks ago. No regrets here. The flow difference is night and day. Only once did the impeller spin backwards upon start up. I put my hand in front of the pump and it corrected itself. I had two stock 6025s on my 55 and was about to upgrade to the 6045s when I came across this thread. I'm not purplexed about the warranty as this has saved me 200 bucks.

I tried the MJ mod and it was too much flow (2000+gph).
Since it looks like this is working nicely, I will try this on my 2-6025s this weekend.
Thanks for the great idea guys!

Can everyone post thier pics of their mod?

Yes, pics please.

I have 2 un-modded in my 55 and i think they work nicely but, i am upgrading to a 90 and want some nice flow.

if you ask me the part cutout helped concentrate and direct flow
if needed, but id rather so scattered flow myself so im gonna try it .
good idea!!

Did anyone try to trim off the front nozzle to the point it is just enough to put the fish screen on? I am thinking by doing so we can get a wider flow pattern. That along with the increased flow after the mod, would make it even better.

Any downside of this you can think of?

Just guessing...If the prop spins backwards, there's nothing to stop it??

And yet you're still going arround and reccomending them in every thread where someone asks about powerheads?


Is this cognitive dissonance rearing its ugly head?

Is there anything to stop it now?

The only thing I can think of is there is less room for the prop to come out during reverse flow, and if it hits the fish screen before it can correct the direction...Guess I will watch one closely in action to make sure there is still enough room after the cutback.

Other than that anyone don't believe the wider flow is worth the cut?

If you want wider flow... stop butchering your tunze nano and get a hydor koralia. :)

One thing youd have to think about it now your running these pumps with "less resistance" or less static pressure on the pump, this will cause the pump to spin faster past its original designed rpm range or pump curve, decreasing overal life expetancy.... cant you tell Im a engineer geek. Trust me tunze has great engineered products and that piece while not completely "neccesary" also was not designed to be removed. Anyway it is a great mod, just curious as to how long these pumps will last.

I have 2 6025's and mine almost always run backwards at startup until I impeed the inlet of flow and create pressure to get the prepeller to run in the right direction. I know they say it is self correcting within 20 seconds but I found that not to be the case, anone else have this isssue also?

I was not aware of these powerheads having this "reverse spin" problem.

If this problem is as widespread as it sounds, how would you use them with a wavemaker?

Do other pumps have this problem?

Mine just doesn't start quite often. I have to unplug it to check on frags in my frag rack and about 50% of the time I have to plug it in 2 or 3 times before it starts spinning.

I bought two 6025's and was thinking about using a wavemaker but given this habit it won't work.

Still, they are very good flow for the prop section of my system.
