flow??? Maxi stream mod!!!

[thangbom]

finally did the maxijet stream mod on 2 mj900 with a octura 1435 prop. and wow!!! i really like this thing!! one of the best thing i done for my tank yet. google 'maxijet stream mod' or 'new improved maxijet stream mod' ( i did the new improved one cuzz it looks better) just need a little know how and your MJ can go from 230 to 1200-1500 gph. sry i cant post pics due to it taking forever ( dial-up) but do the google and you can see plenty of pics

looks good but how directed is the flow?

 

[thangbom]

the mod totally changes the flow pattern on the MJ. the old mj w/iplellar is more of a 'jet like flow and dont really disperse. the mod turns the flow into more of a 'wave/current' it is only really strong the first 6'' or 7'' then it get more disperse. i placed a small tube close to it to pull a vortex to see the bubble/stream pattern and about 12'' away it is about 11'' wide. this thing can move some water. my moded mj at 4'' under water can pull a vortex by itself. try a google vid search. think there is a vid on it.

I am fixing to mod a 1200 myself. I should have the pump in today or tomorrow. I have heard great things.

im telling you this thing is great . the only one bad thing i can say about it is that it do make a little of a hummmmmmm. it's not tooo loud and i get use to it afther a few hrs. i used the octura 1435 on a 900 and it moves a lot. i should of ordered the next size bigger to for kicks. just to be able to swap them back and forth and see what i want.. and gl

Thangbom,
Did you make the mody yourself. I just got my maxi modded and I can not get the prop to turn in the right direction. I have not put the stop rod in, but I can not figure out how and what the stop rod does.

 

[psbrent2]

The stop rod will catch the prop if it is pulling water in and cause the pump to reverse. The prop should slide a bit on the shaft, when it is pushing water out, the prop will not hit the stop rod. When the prop is pulling water in, it will slide out and hit the stop rod. Just did a 1200 myself last night.

I finally got my maximod working. I did not have enough play on the clear tube that the prop is glued on. Now it works like a charm. I am allowing the attachment for my aquarium to dry and I wll put it in my tank tonight. It is going into my 29g. I will see if it is too much. But I have a 90g coming around christmas time, so I know it will work there.
By the way Honda East, I live in Toledo and have been to Honda East many times. I used to have a honda rebel. Now I have a torn apart 1978 750K. I live at Douglas and Lasky? You?

Good Deal...
Mine is drying today as well, I will put it in tonight.
I live about 40 minuteswest of Maumee, out in the country...

i actually made the whole mod myself. i dont like the look the MJ***.com sells. i only ordered the prop and 316 rod from him ( sharky). made the rest on the table saw and dremal. So how do you guys like the mod??? i love mine

I tried my mod from MJMods in my 29. There was a lot of vibration noise, that i did not remember from my trial runs in my sink. Does yours have vibration noise? If so, what can I do. Also, I believe that it is too much flow in my 29. I wanted a little more flow since I have gotten some SPS frags. Buts since my tank is predominatly softies and LPS, I think I will ahve to wait until the 90g is up and running to use the maxmod.
Does anybody know if you can hook up multiple mods to a wavemaker/surge device?

 

[thangbom]

it vibrates because it's out of balance or assembled to loose. when i made my mod, i made it a snug as possible so that i dint have to glue anything except the prop to the hard airline. all i have to do is twist and turn the pieces to find the 'sweet' spot and no more vibration. as for too much flow, cant you turn the maxi so that it face upwards?
