The "Hitchhiker's Guide" to the Maxi-Stream mod

Actually I'm in process of setting up a 120g, what do you guys thing about flow out of 2 mj900s with 1.25s and 2 mj900/1200s with dual 1.25s. Will that be good or would I be better off with 2x1.25's and 2x1.75s?

If I go with 2x1.75s and not dual 1.25s. If that won't be to much I've got 4 extra 1.25 dumas I could trade for 1.75s or octuras. But I don't want to end up blowing rocks around the tank either.
 
well dont run the dual props, i think that kinda got overruled by some of the octura props and i dont see any benefits of runn tow props vs. 1, if the motor can spin 1.25 and you want more flow than the 1.25 offers just go one prop size bigger and run it as a single.

2 1.75s on MJ 1200 is gonna be a lot of flow, if you have sand it will be a blowin', 2 or 3 900s running something a little larger than the 1.25s might be a better choice.

heck i am only running 2 1200s 1.75 props in my 180 and i have one set to turn on and off throughout the day, it is a lot of flow

These pumps do have the advantage in that their impellers are fixed, as in, no need for a cross-brace on the prop shroud to hold the prop straight.


I put a plastic pipe in part of the pipe to prevent the pump from spinning backwards, just like a MJ. It was dead simple, easier than a maxi, and not permanent. Oh, and dead silent.

Oh, and if you want a real monster, I hooked up dual 2.3" Octura props to the Aquaclear 5000 (now called the 901). That 59watt monster usually puts out 1000gph, but now...lol...its gotta be over 6000gph. I ran it sidexside with my cousin's Tunze 6200s, and the modded 901 simply blew it away.

Hahn, im have a little trouble visualizing this and what keeps the prop from coming completly out of the pump do you have any photos "I put a plastic pipe in part of the pipe to prevent the pump from spinning backwards",

901 mod sounds great. i got to do this 901 mod. i might to make a few extra of them on my canoe:)

thanks guys, great info

rioratholenm, u can switch but u will have to change out the magnets. thats the only difference is the magnet is bigger on the 600 than the 400.

Are you running single props on the 1200's?

Here is a link to the Aquaclear 101 mod in progress...

http://www.nano-reef.com/forums/index.php?showtopic=83527

The ceramic shaft of Aquaclear PHs are fixed into the motor at one end, and the magnet keeps from coming out on its own magnetic self. This is true of the whole Hi-Spec Aquaclear line (ceramic shaft), the regular line (steel shaft), and Penguin powerheads (steel shaft).
Click to expand...

Did you mean if the prop turns in opposite direction the magnet will not move therefore it will keep turning at the wrong direction?

I was hoping the magnet will be pulled out by the force of the prop the same way as an MJ. Even if it just gets pulling out a little bit then a stopper will be able to do the trick.
 
No no no...with the AC101, if the prop moves the wrong dierection, the prop&impeller assembly actually pops out about 1/4"-3/8" on its own...enough that it resets itself in the right direction w/o a brake really. But just in case, I will add the brake to the shroud.

What I was saying about the AC101 is that the shaft is fixed...the magnet and blades arent, but the ceramic shaft is fixed in the pump, so there is no need to make a new, longer shaft to run through the whole assembly and meet the shroud with a cross-brace. The shaft is fixed in place...thats all. It makes the mod loads easier. No SS or CF rods to buy and cross braces to attach to the shroud.

At that, I know that the primary advantage of the MJs is their known compatibility with wavemaker timers, but it seems that the violent startup of the props means that its only a matter of time before the brake and prop constantly hitting each other means breaking, and a whole lot of noise every time the MJ starts up. Im all ears if there is a way around this, but it seems that a better option would be a rotating/oscillating powerhead mount so that the modded pumps can stay on all the time and still make random currents.
 
Good to hear. I don't think the repeated on and off itself is an issue, powerheads are used that way all the time. If the Aquaclear PHs can reset themselves quietly, then they will be good enough for me to put on a mavemaker.

A rotating mount will be nice but if things get too complicated, too difficult to mod or mount, or too expensive, the mod loses its appeal fast, and people may as well spend the money on Tunze and be done with it.
 
if people just bought tunzes what would we do with our "DIY time" i wouldnt have an excuse to be in my basement workshop for hours at a time. lol:lol:
 
The thing is DIY is not ALL about saving money. Most of the time saving moeny IS the biggest reason to DIY but it's not the only reason.

I DIY because I enjoy doing it and get a certain satisfaction from actually creating something or making something work better than the original product. Granted getting a Stream like pump and performance out of a Maxijet for pennies is a pretty BIG incentive for DIY :D

Yeah, and the Aquaclears are just that much easier to mod than a MJ even. If you can get your hands on the Hi-Spec 2000, 3000, 4000 models, you can just remove the shroud, pop a prop on the shaft with air tubing, and away you go!!! (Ok, be sure to zip-tie on a shroud or something too...but thats it...)
 
I dont know much about this project but would it be possible to use a t mounted directly on the first fitting, put mesh over them, remove the stopper from the design and put this on some sort of a timer so that it goes of every few minutes and comes on pushing the opposite direction of the way it was going to achieve a wave effect.

Any reason the regular Aquaclear PHs (301, 401) would not work? BTW I thought the Penguin PHs have floating shafts just like MJs.

i need 6 of them so i could do a bit of messing around and spend like a total of $150 or I could spend $1200 on tunzes, depends on how much your time is worth. If i can save over $30 a hour with DYI its worth it to me . this project is more like $60-70 an hour. not to mention some people just plain old cant afford the tunzes so this is an excellent solution. there is also the pride factor : )
 
well orderd only three dumb me should have done more of the 1.75's for my 900 and one 1200.. i have three 900's one is missing the magnet though.. anyone know of a cheap place to buy a new one.. also on the seio mods anyone try the bigger octura prop yet.. setting up a 290 and thinking of running the maxi's (4 ) 4 eductors, and a sequence 4200 closed loop.. lots of flow.. and maybe two modded seio 1500's YEA maybe should stick with the .175 dumas for the seios.. two on each 1500 or step it up a bit?
