My Maxi Mod

[JMBoehling]

Here is a video of my Maxi-Mod at work. I will make a more asthetically pleasing shroud on Monday and repost some pics. The flow is extremely wide and random with my design.

Enjoy!

Wow, Jim thats looking pretty cool. Are you running any other powerheads in that movie, or is all the flow from your MJ-mod?

[JMBoehling]

Just flow from the One MJ1200 and my return pump. I will bring a Mod to this Saturdays meet if someone has a spare MJ 900 or 1200 to adapt ..

The great thing about my Mod is you utilize the existing components of your Maxi jet. All you need is a 1435 Prop, couple of parts from Lowes and your ready. This thing is painfully easy to make, and no noise. I would recommend putting this on some sort of wavemaker to get the benefits from the alternating current of the pump..

I plan to have 4 of these in my 90 on a Wavemaker or timer.

[J. Montgomery]

I've got a spare 1200 that I'd like to mod; I'll bring it. And I believe the meeting is on Sunday.

Since I may not be able to make it can you post pics of the build?

I will take step by step photos on Monday when I have a second to construct the even better "Jim's Mod"

Nice job Jim! Can't wait to see what 4 of them will do to a 90 gal.

Create WAVES!!! I have made 2 of these and both work awesome. very quiet and will cycle on and off on a timer with no problems.

Good luck with your Jim's Maxi-Mod...

Cool Jim.....How much flow do you get with this mod of the mod?

How long does it take you to fill a Gal sized ziplock bag?

No clue how to even attempt that test.. It is enough RANDOM flow to keep my BB stirred up nicely and my SPS waving in the breeze and the bottom of my reef Detritus free... Plus it is simple, quiet and very inexpensive to make. I am now wondering if there is a better prop to use for this mod... Oh well, I'll let someone else figure that out.

We'll make one this Sunday at Marvins. I've got all the supplies in hand, and someone will go home with it as my contribution to the raffle (Since I am NOT Nudi free and in a position to trade Frags..)

[Rothie]

Jim-
Thanks for the info and pics.Do you know the name of the PVC piece you are calling a plug(what it would be called at HD)?

[JMBoehling]

1 1/2" Plug Spigot. Lasco part # 449015RMC from Lowe's. I only wish they had some Schedule 40 in gray in stock

[twon8]

nice job. i think if you went with two of those and one regular mod you would be set.

one thing you might want to consider is some sort of grating over the output to prevent a fish chopping.

[JMBoehling]

Here's a movie with both mod'd 1200's running. I threw some food in the take to show the flow.

More Flow!!!!

Later,

Jim

I am hoping my 6-Line will swim into it!

[J. Montgomery]

Wow, I'm impressed. I like how it has a lower profile than the normal MJ.

[Rothie]

Thanks for the part #.Those skylights are doing a fantastic job!What else are you using for flow besides the modded Maxi Jets?

[angelscrx]

I like it. Seems simple enough that I may even try it.

[rick s]

Looks great Jim! Thanks for the play-by-play. I'm looking forward to seeing these mods perform in a tank in person.

[Malifluous]

Thanks for the instructions. Please show us how u made the magnet set up for the corals on the wall?

[reefdadx2]

Thanks for the great play by play on how to do the mod. I think this one will catch on quick. Michael R

[impur]

In the video it looks like the MJs are pointing down? Is the flow shooting straight to the bottom of the tank?
