Wait Ben, where is the power cord on your 6025? Did you do some special mod but not telling us?

that is a pic i took off the net via google image.

my nano's are mounted on top of my eurobraced tank rather than on the side of the tank.

believe it or not...i like the look of the nano's in the front of the tank even though i could easily move them to the back.

with the nano mounted on the euro bracing...there is NO electrical wire visible and the result is a very very clean look.

i have a convention to attend at this very moment...

when i get back, i'll take a pic of it!

"its hard to find a thread lately without him proving us all to be idiots with his greater knowledge of all that is talked about on RC"

Rich never fails to be nothing but a anoying buzz kill. Everyone is happy with their nano's being a 1/3 the size of the maximod, a sexy look, and producing great flow. Whats the big friggin deal... this guy just really ****es me off. Hes the same way on the boston reefers forums... Nothing but useless banter, thinking HIS way is the ONLY way for everything, seriously Rich you need some prozack or something.

...

Holly C%$#! I never thought of that, my eurobrace is only 1" above the water where my 6055 is now:

I will definately try to mount it there next time and see if it would work and how it would look.

jacmyoung I like the look of your table acros. Do you have tank photo that is clearer?

They are faux coral, there is a full tank picture a few pages back.

Armed with the knowledge that my 6055 super-mod with the Stream 6100 prop was still some ways below the max motor rating, I did the unthinkable, and slapped a 6200 prop on.

The 6200 prop is much larger in diameter and pitch than the 6100 prop. As a result it fits even more perfectly on the Aquaclear 110 filter magnet driver, almost as if they were made for each other. But the diameter is too big for the DIY shroud. Additionally the unmodded 6200 prop would draw 1.6A in full speed, so some trimming was in order.

While doing the trimming, I realized I could even fine tune the trimming of each blades to the point that the unit was so balanced it actually had less vibration than that from the stock 6055 prop.

I am not talking about noise since both were dead silent, rather pump vibration when turned on. The vibration always exists, it can be felt while holding the live pump by hand, but the advantage of hand trimming the prop. vs. mass produced prop. is you can achieve more balance even with the much larger prop. and at much greater force, if you trim the prop carefully and properly.

In any case below are the stats with the slightly trimmed 6200 prop on the 6055:

Total watts: 35W (by Kill-A-Watt meter);
Total AC current: 520mA (by Kill-A-Watt meter, 6055 transformer max is 800mA);
DC current: 1.13A (1.2A max for both the transformer and the motor);
DC voltage: 23V;
Estimated motor draw: 26W;
Estimated transformer draw: 9W;
and the controller's draw is still negligible.

And the flow is about 2,900 gph, very closely tracking the Vortech pump.

Now I am going to put this little monster in the tank on 30/100 pulse for an endurance test, someone wake me up three months from now when you all have your own 6055s, and I will let you know if my little monster is still running strong or has succumbed to a fiery flame.

I did the mod and connected it to two swirls tonight. Glue is still drying, they will be running tonight. I did it a little different so I could manuever the pump and take out for cleaning.

What do you think?

 

[mano1192]

now thats a cool idea but what about he cord? will it get wrapoped up as it spins?

jacmyoung... That's called prop balancing what you did. This is what RC boat builders do to get the best performance from the propellers. The more balanced the prop = the quieter and less vibration which means less resistance + less drag = better performance. You can really fine tune the propeller by using a propeller balancer like the below:

I DIY my own Mj mod for about $10 in parts plus an old MJ1200 I had in hand with enough leftover parts for 3 or 4 more mods. So this argument about modding a MJ pump costing more than the nano is BS IMO. If you can't or unwilling to DIY then obviously the MJ mod is not for you. The majority of the cost in the kit from MJmods.com is in labour. It takes time to measure and cut the shroud, etc... Time is exactly what you are doing with the nano mod IMO. If you translate that time to dollars, how much do you think the nano mod would cost ontop of the cost of the pump already?

3000gph is also stretching it a bit I think for the MJ mod. From my own testings, the MJ mod spinning the Dumas 3004 propeller is more like 2000-2400 gph range. Not sure about power consumption as I don't have a kill-a-watt to test that. 2000-2400 gph is not even in the same league for a modded 6025. My modded MJ600 (7.5w stock) can easily put out more flow than a modded 6025 with the modded MJ400 (5w stock) feels about as much as the modded 6025.

Remember too that the "MJ mod" can be done on ANY submersible pump and powerhead and not just Maxijet so you can actually do it on any powerhead you have lying around . I've done successful mods on AquaClear, Mag 3, JBJ, Penguin, Walmart's Regent brand ph, even JEBO pumps.

IMO if you are going to mod, why not start with a cheaper pump in the first place? I also think it's kinda funny how a lot of folks tout Tunze being the "best" pump this and that, buy one and then hack it up to pieces to make it better... Kinda an oxymoron IMO. Not that the Vortech is without its own issues, but you don't see anyone modding that pump do ya.... Something to consider.

But to each his own I guess.

dhnguyen, thanks for the prop balancer info. I do want people to be aware that while the conventional prop balance works with hobby boats and even MJMods, it may not be very useful for Nanostreams because the shroud openings are not evenly distributed. The stock shrouds open up more on the top while the full blast mod opens up more at the underside.

The way I balanced my 6055 mod was admittedly more tedious than most people would care for. After sanding down the 6200 prop so the pump draw was 26W and 1.13A, I began filing down on each blade in very small increments, each time putting everything back together and tested as if in real use, after the back and forth filing of one or both blades, eventually arrived at the most balanced state. And in the end the two blades are not precisely the same size, in order to cancel out the uneven flow through the shroud. In another word the balancing of the 6055 mod will be very specific to the magnet driver you use, how much you sand down the driver part, the prop part, and how you build the DIY shroud. Not to mention the loss of warranty. That will be enough to deter most people from such attempt.

Another thing is you really should invest in a Kill-A-Watt meter, it is dirt cheap and give you instant watts reading. You have quoted the stock watts on MJ400 and MJ600, but I will bet when a bigger prop is used to pump out more than a stock 6025, they also consume more watts if only you had the meter to tell. IMO MJ powerheads are probably some of the least efficiently built pumps out there, they all seem to have big enough motor mass (re more material cost) to be able to go up to 30W, yet are sold for much smaller use, by putting smaller impellers in. You simply can not use the so called stock wattage as your MJMod reference power draw. Of course one manufacture's inefficient design is another DIYer's blessing.

After many practices on the Nano mods, I can do the standard 6025 mod in less than 5 minutes, and the full blast mod another 10 minutes. So time is on the nano mod side too.

As far as modding a Tunze being an oxymoron thing to do, you certainly have the right to your opinion, just you know one of the senior RC members commented that he thought of the same but after reading this thread he had completely changed his mind, and so can you my friend

But to tell you a secret, what I really hope all these Tunze Nano Mods do is to pressure Tunze to come out with newer and more improved nano pumps that can rival their own stream pumps and the Vortech, and may be more other new pumps on the horizon. I know for a fact after talking to Hydor preps that they are working hard on more powerful Koralia pumps and a controller too.

The good thing is Tunze already has the Nanostreams foundation built, and from our mods we know they can easily roll out more powerful version of Nanos. Of course whether they will do so we have no control over. Maybe they don't want to cut into their Stream pumps sale, but that would be very short-sighted.

DH, alot of this thread, was as Jacmyoung said, to get tunze to change. Read back to the first few pages, all the different things i found to make it better, i wrote tunze should do this, tunze should do that.

This mod is also extremely easy. I did it with a hacksaw and tin snips. Like said before, i have a small tank, i dont like alot of pumps, or big pumps, so this worked great for me .

 

[GSMguy]

i think that tunze is watching us
at least Rodger is

the new redesigned turbelle stream pumps will be taking a few tricks from the nanos i have a feeling

 

[NewSchool04]

how loud are your 6025's after modding? Mine seems to have a definitive hum or even growl.

mine stayed silent how long have you had yours?

 

[NewSchool04]

just started it up 5 minutes ago

 

[GSMguy]

take your hand and cup the pump while it is running sometimes the shroud is a lil off and it vibrates until you properly secure it if that wont work give it 24 hours. then they quiet down
most nano stream Reviews cited vibration during the first 24 hours. my origional 6025s did that my replacements did not.

BTW Tunze customer service is so good rodger replaced both my pumps even though only one was making noise.

this is the very reason i got the nano streams.

i prefer to have ph's in my main display over a closed loop...but:

i absolutely hate the look of full size streams. i also do not like the rough appearance of modding mj's.

the nano's have been what i have been looking for. very small size, decent flow (after modding) and a pretty aesthetic appearance...much more so than a hulk of a pump on an equally hulking magnet mount (reg streams) and the aesthetic rounded appearance which is better than any in tank mounted pump i have seen yet imo (both reg streams and mj modded).

vortech?

one day.

they seem to be very young in its development still but have great potential if they can find some way of directing their flow and controlling their flow (yes, i constantly hear that the controller is coming out).

directing flow? yep, i would love to put a vortech in the back bottom corner of my tank. i would need a 45 degree bend to do what i want. yes, i have read that the vortech gives a great dispersed flow but that's not what i am asking now, am i?

thanks for the mod thread guys! it was this very thread that convinced me that getting a few nano's would solve a lot of what i was looking for. and the way i see it...as a consumer, if i was looking for this...i am more than certain that others are looking for it as well. it is up to manufacturers to realize this and cater to our wants and needs, otherwise, someone else will and profit from that.

Thand GSMguy, I'll try that.
This pump on my swirl is unbelievable and I haven't gotten the second one on the tank yet! I'm having problems fitting the swirl to the back of the tank, it's too close to the back wall. They may have to be side by side right in the middle of the tank going opposit ways. I'm out to Home Depot to see if I can find some nylon screws that are a little longer than the ones that came with the swirl.

newschool,

looks like you gotta get that submariner a little more wet in the tank!!!
