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

Horace. You should do a search on RC for SEIO and see how many people have complained about them seizing up and not starting. You won't have to worry about that with Maxijets. :)

D.
 
Agreed, the Seio is a pain to use. I have three and everytime I do a water change I have to work on at least 2 to get them restarted. I am thinking about going this direction.
 
I don't like Seio because it so bulky.

My wife likes the looks of my Maxi-Streams better too.
And thats a good thing. :D
 
The main advantage to this mod is size. The maxi mods take up a lot less room than Seio and Tunze pumps.
 
my experience with the seios are that they stop often.
i'm thinking of applying the maxijet mode onto one of my seios.

yesterday i mounted the m600 mod on my 240 and the flow is fantastic. my tank is 8' long and i'm not sure it could handle more than 2 of these mods.

Spoken like a true married reefer Kevin :)

You have no idea how long it took me to aquascape the tank because the wife didn't like the way it looked.

Just thought I would throw out a couple ideas on what I have done with my latest prototype.

First, I ordered some Seio 620 swivel mounting brackets. I then glued them onto a magnet cleaner and came up with a 100% movable in all directions, mounting solution.

I used a 1.5" PVC coupleing as the housing. I also used a 1.5" prop. The prop fits in the housing, but the flow was greatly reduced, no matter how much intake slots I made. I couldnt stand for that. So I took out the dremel, put on a round sanding drum, and took out material from the inside. This made more space between the blade tip and the edge of the housing. This increased flow so much that I couldnt tell a difference between the prop without a housing and the prop with the housing on. Im finally happy with the flow results. I stll have to measure the exact amount, but its over 2000 GPH for sure according to past tests I have done.

I still need to clean up the craftsmanship, but I finally have a working model to base the next attempt at. Im looking to make a couple more of these to finish off the lineup. This one will go behind the rockwork eventually.

Cool idea with boring out the ID of the PVC coupling. I also like the idea of using the SEIO mount for this :)

Did you paint that housing? Or did you find the dark gray coupling somewhere?


D.
 
Thanks.

I painted the housing. I used a vinyl spray paint that is supposed to bond to plastics on a molecular level. Im hoping its reef safe. I dont see why not.
 
You should be fine with that paint. I've been using Krylon Fusion for quite some time now without any issues. Just be sure to let it dry and cure completely.

Vrey cool idea with the SEIO mount. Where did you order them from? Also, do you see a problem with flipping themm over so the mod hangs below the magnet? That would get the mag/mount out of the way & the pump would be deeper.
 
I got the Seio mounts directly from Taam. They are not easy to order from.

You could easily flip the mount over. I chose to keep it up because I want the pump to be higher in the water and not hang down a few inches into the tank. I wanted to hide the pumps in the upper corners as much as possible. The maxi mod doesnt suck much air, so you can have it pretty close to the surface. Plus, with the ball joint, you can point it anywhere you please.

I assume you're referring to the 1.75" Dumas prop. Use the 3/16" ones because that would fit perfectly over a 3/16" rigid airline tube.

Keep in mind though, if you're doing the 1.75" Dumas prop mod then you're going to have to be a little more creative with the housing. The 1.75" prop won't fit inside a 1.5" PVC pipe and the 2" PVC pipe or 1.5 slip coupling will be too big for the MJ alone.

I just tried the Mod with my MJ 1200 using the 1.75" dumas.
I got the 3/16 hole size, but realized this is a left handed prop.
Does this matter?
It is always spinning backwards. I know i can make a stopper but usually plugging/unplugging makes it spin the right way.
This does not seem to happen with this left handed prop.
Is this the same prop you are using? I can seem to find a right handed prop @ 1.75" X 3/16 hole.
This is the one i got:

OK!
Dhnguyen! and everybody else.........

I dont think that my stupidity is really that much that makes me scream
with open lungs.........................

ARRGHHH!.

There is a FAQ on page 30 http://reefcentral.com/forums/showthread.php?s=&threadid=717034&perpage=25&pagenumber=30

Q: Why won't my mod spin correctly or at all under water when it spins fine outside the water.
A: Either you have too few of the inlet holes and/or slots on your housing or that they are too small.

Do you have a photo of your housing?

It shouldn't matter whether it is left handed or right handed prop. But you do need to have the stopper in order to prevent the reverse spinning.

D.
 
Thanks D.

I was able to make it run for a bit & this thing puts out some serious flow. I will be putting a stopper. I would say close to 3000GPH. I compared it to my seio 1100 & it is easily 3X stronger.

Are you also using the Left handed prop? I don't think tower hobbies has a right handed prop with a 3/16 shaft hole.

My coupling is approx. 2.25" long, does it make a difference if i cut it down to 1.5" like your latest one?

thanks again
 
Most propellers sold are left handed propellers unless specifally listed otherwise. If you do use two propellers on one mod though, you HAVE to be sure that they're botht the same whether right handed or left handed. Having one right handed and one left handed would work against each other.

Where did you order the mounts? I cant seem to find it on their website. Their site sucks BTW :(

You have to e-mail them. They will then send you a form to fill out and mail or fax. I didnt want to do that so I ended up talking to them on the phone and ordering them that way.

If you are going to mount it to a magnet, then all you need is the swivel bracket. If you want to mount it hanging on the tank like a seio, then you need the entire mounting kit. The swivel bracket cost half as much as the entire kit. The 620 mount is the smallest and holds the maxijet perfectly.
