Its incredible that you got that much flow out of a MJ600. I have a few in operation that I am thinking about doing this mod too.
Looks like Its off to Home Depot and a Hobby Shop. Just a question, what did you use to hold the end of the propeller shaft at the end of the mod? Also, do you have any other pictures of that cap that you used to clip the thing on, or more info on it. I havent seen them in the stores around here, but then again, I havent been looking. What size is it? Again, thanks for the detailed instructions. Hopefully I'll get a chance to do it today on one of our 600s, and possibly make a few more for our other power heads. Could save a bundle on Seios for our new tank. |

I will get you the part number of the cap when I get home, I got it from Lowes.
As for the propeller, everything was attached with Gel Super Glue. I may try some different types of glue, however the Gel SG is holding up quite well. Oh, also wanted to mention something about performance. At first, when I dropped this thing in the tank, it was making a slight clicking noise from where the magnet was tapping the side.(I guess from not being perfectly centered. However that noice is completely gone now. Have not heard it in the last 3 days. On the next rendition, I am 100% possitive I can make this thing perfectly centered in the PVC. I can't wait to show everyone what I have come up with. Should be pretty slick Wayne |

This is the best iteration of a DIY stream I have seen yet. Gonna try it with a 1200 this weekend.

I cant even imagine how much flow a 1200 would get. I'm gonna try making the nozzle attachement for our 600s and see how that goes, and since it is nearly interchangeable, we'll probably invest in some 1200s for our 150, and put it on a wave timer like you mentioned earlier.
The flow out of your 600 is incredible. Our 900 doesnt do it for the 20 long prop tank we've got (wth a skilter 250 and Emperor 400 HOB) so that one will probably get moved to our 40. |

One question: What are the washers for? I don't see in the pics or the description where they get used.

If this works so good with a 600, I am wondering if there would be any benefit at all using a 1200. Does teh 1200 turn faster? I am also wondering about the current draw of a 600 and a 1200 with this mod. Is anyone willing to measure the current?

I tried to make one with my 1200 and it doesn't work very well. I don't know if I did something wrong but it is very noisy and seizes a lot. If you don't have enough holes in it will it do this? I pretty much did it the way described here other than a couple different parts but mine sucks. Any suggestions?

well I have taken it apart now and I'm trying something else. Basically I did the same as you I cut the blades off the impeller and glued the tubing to the impeller and then glued the prop on the end of the tubing. I didn't have the ss rod perfectly centered on the guard could this have been the problem or is the prop too big?

Also, you may want to wait and see what I do on this next rendition before going any further as I am going to address the gaurd(Rod stabalizer) as well as a stop for when the blade turns in the wrong direction. That way you do not need to stick your finger in to stop it. Wayne |

Concerning the wrong direction... why can't the original impeller design be implimented to make sure it always turns the right direction?

I would like to see more of this.

Wayne,
I don't know if it's been mentioned or not, but what is your plan for producing a stop so that the Maxi-Jet prop does not turn in the wrong direction? Peace, John H. |

I got mine to work but when I put the guard on it seizes. It doesn't seem to be hitting on the sides. Any ideas?

I am going to include the fix this weekend and post the pics once I am finished. It would be harder for me to explain than to just post apic of it, but it will be very clean and 100% effective. Thanks for the recomendation though. Wayne |

One of the biggest differences between the 600 and 1200 is the impeller. Since your essentially removing the impeller, theres not going to be as dramatic a difference between a 600 and a 1200, tho the 1200 is a little bigger with a bit more power behind it.
FWIW the plastic piece that holds the impeller in and lets water in and out of the powerhead (do these have a name?) are different sizes, barely. I could not get one from a 750 to fit onto a 1200. The impeller on the 1200 is a little longer. Shouldn't matter for this mod though from the looks of it. For example, if I'm not mistaken, the only difference between a Rio 2100 and 2500 is the impeller. I wonder if playing with different size propellers will give you different flow results. A bigger propeller on a 1200 may give better results. What happens if a fish swims into it All in all, very impressive...may just give this a try! |

No prob Wayne, not rude, I have been trying to follow, but I guess I must've just missed it.
Can't wait for the pics. It'd be really nice if we could set this up on a wavemaker! Pics are definitely worth a thousand words. Peace, John H. |
