Tunze nano mod

well what would you like the video to show? i showed the corals movement and the flake getting blown around

what were you expecting?
 
I finally had a little time for myself to do another mod for my already modded 6025. I decided to cut a few slots on the underside of the shroud for several reasons:

1. I noticed with the increased flow, the pump tends to draw some air bubbles if too close to the surface;
2. The underside of the shroud is the closest to the prop so a potential to maximize the flow;
and 3. If my slots don't look good, they are not that noticeable.

After the mod, I can say by the feel of my hand the flow is very close to when the shroud is completely taken off. And we all know that is a lot of flow. I don't have a way to test it but my guess easily 1,500gph. Also the pump now can be less than one inch from the water surface without drawing air.

First is the standard mod:

This is the "wide flow mod" where the from part of the shroud is cut all the way back to the ball, leaving only enough room to put on the fish screen:

Now the "full blast mod":

When I get around to do the same mod on my second 6025, I hope I can do a better job and make the slots look nicer, if anyone can offer some pointers on how to do so with a dremel please tell. Maybe I need more than just a standard dremel kit, maybe a guide?

But first thing first, how do I display the photos directly in my post? I used to just unpload to RC, now I am using Yahoo Photos from my DSL account.

Definitely more than the standard mod. I can honestly say it felt like the shroud was off.

BTW a word of caution the "wide flow mod" will not allow the pump to self-correct the flow at startup so don't do it if you don't want to disable that function.
 
i want to do the standard and full blast but not the wide that will be nice to make it more effective at 3ft

The full blast easily blasts those little dandruff in the water across the length of my tank (4') and then bounces them back some more. With my other 6025 on the other end pointed at each other, they all ended up crashing at the center of the tank.
 
id love to see a short video of the full blast mod before i try it

last time i did a mod my tank went crazy for days with all the dtrritus it blew up, i dont think i haev any dead spots right now, but i dont want to kill the zoas in my tank either
 
I got a 6025 for 30$ today(1month used)
I'll do the mod tomorow but where to place it in the tank?

got a 36x16x20 50g tank and if I place it on one high side pointing at the surface and front, it's blast a hell everywhere.
My xenia is 3" off the sand and in the middle, and it's already high.

I was even getting sand tornado 12in tall ever 5min lol
 
i couldent stand to look at my seio anymore so i have actually reduced my flow i need to add some more now
 
well i got bored and drilled a 1/2" hole in the front tube right below where the impellars rear end it, and i do feel the suction coming up right from below, which adds flow from below the pump, moving more water around. If you put your finger over the hole the flow is reduced, however with the small hole i did it is not by much, but there is an increase. if you cut large slits like he did there will be much more of an increase

now if only this pump was silent, it is the only thing in my tank that bugs me, i love the flow nad the look of it, its just a loud hummmmmmm

my tank is dead silent when the pump is off, i managed to silence my overflow adn the return running in from the fuge, but this is just a hummmmmmm i can hear from outside my room and down the hall maybe like 10 feet if the door is open. it sounds similar to a fan, just different, its a steady pitch, which makes it manageable for sleep though, which is good


i think this pump is amazing now with the mods though, thanks for everyoen who has pitched in, and did some testing of their own, and keep on making this thing better!

once i get a job(turn 16 in under 2 weeks) ill start playing around with it more, like buyign the different motors, and impellars, mixing and matchign different parts with different mods, to try to get things perfect for different setups.
 
yea, i know some are silent, some are loud. Maybe once i get a job and a steady income ill buy another and see if it will eb silent, if it isnt ill send it to roger to make it silent, then mod it haha
 
i have 2 uncut 6025's and hope my fish dont get to upset b/c i already have 2 6100's and a multi-controller in my 3 ft 24 inch deep 70 g oceanic will mod on Sunday for a little project with the dremmel
 
if ones just does the standard mod where yo dremel the inside out of that housing piece, does this void the tunze warranty ???
