Tunze nano mod

I think he was wanting to know how to do the Nano Stream 6025 MOD

Bump for this mod. I intend to do the the standard mod and the FBM. Will I need a stopper in order to keep in going in the proper direction if I do these two? Didn't you say there was not much of a difference between the hard stopper and soft one as far as noise? I don't really want to do the WFM if I don't have to.

My experience is after you do the mods, the 6025's self-correct mechanism will be less effective if working at all, however if you run the pump 24/7, there is still no need to do the stopper mod. When you have to switch it off, at the on time just switch it on and off several times until your pump spins correctly. Use a 2-prong switch for that purpose.

I do not like soft stopper on the 6025 since mine ended up getting the prop stuck, and eventually contributed to the breaking of the shaft, but I can only speak for myself on this one.

Again 6045 has no such issue, the hard stopper is built-in.
 
did the mod to all 4 om my new 6025s i think that will put me at 4000gph on a 150 with my return bringing me to 4500 so 30x turn over hopefully that will be a start for my sps tank

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.

I am running (2) 6045's with the basic mod on a Seio controller and I'm getting a lot of pump clattering noise especially when the controller throttles down from 100% to 50%. I assume that this is because of the mod that I did on the pumps. Is anyone else experiencing this? Can I stop this from happening or will I need to go back to unmodded propellor housings?
 
i have read where seio are higher wattage pumps
being that when it throttles down you are going to have problems with bringing it down to 4 watts

Turned out this member needed line conditioning for his power source.
 
Thanks, jacmyoung. I have a UPS that has a built-in voltage regulator. I'll plug it in to that and see if it works. If not, I'll see if I can find a dedicated voltage regulator.

I am happy with my 6045 too. Skydancer's comment was made long time ago so it could not have been an insult to you since you only bought yours a month and half ago.

The point to be made is in the early days when we had just a few 6025s around, even fewer were the 6045s, when we discovered that the 6045 was not pumping out 1189 gph rather 950 gph, and 6025 was not pumping 660 gph rather 770 gph, and after some mods both 6025 and 6045 were pumping the same 1250 gph, and with the stopper mod on the 6025, it was identical to 6045 in any way you saw it, so yes spending the extra $30 did not seem a smart move, and many 6045 owners felt the same way.

Only recently we discovered some strength and benefit of the 6045. And I just did not think it was a wise thing for dga to bring back a very old post trying to make a point of how he knew how much benefit his 6045 has, because I know for a fact he just bought his 6045 very recently, after reading all the information in this thread, most of which the result of hard work by people like skydancer, and then to use one of his earlier comments to show off your own 6045 purchase? How did you see that other than being a cheap shot?

Some of the strength of the 6045 were discovered purely by chance, my guess is had I not brought up such points about the 6045, dga would not have even realized that and probably would have come here to complain how he was cheated by Tunze.

Another thing to be said is if you don't mind doing the stopper mod for your 6025 (which is more complicated than the flow mods), a modded 6025 is still the best stream pump out there with the best value, no question about that.

so are we still at 1200 gph or has it decreased with new test on the 6025
 
Thanks guys! mod-ed my 25 last night for alittle extra flow and really appreciate the tip. So easy to do. Couple of pics

I might do more but for now I like the flow im getting.
 
I finally did mine, what a huge difference!
My nems and corals had to get used to the extra flow, took a couple days for that.
I even did the shorter barrel mod for wider pattern.
Used a rubber band for guide to cut straight.

i did my 6045. Shortened the barrel. put in a stopper and dremeled out the inside for more flow. Wow is is crazy flow now. All the corals love it. I just got fish though and I think it may be a bit too much lol. Had to angle it off the glass a bit.

Cool idea doing free hand.

My 6045 with the modded 6055 larger prop is still kicking strong with near 1,500 gph. I would say it stands the test if it will last over a year.

Unfortunately the 6055 mod (near 3,000 gph) did not work out only because the Aqauclear magnet wore out too fast.
 
Update:
All 4 of my modded 6025s are running good. 1 hour on 1 hour off. Only problem, one stopper broke and now I'm running it without the stopper. It was probably an operator error on the stopper, as I probably had cut it too thin to begin with.
