Thanks for the response. Here are my follow-up questions (same numbering to avoid confusion):
1. OK, I have a bunch of that stuff lying around that I use on coral frags...
2. So if in my 75g I put 2, single Nitro prop 900s on opposite ends of the tank and opposite sides (one left/back side and one front/right side), that would be good? I've seen many placed in the back corners facing directly forward...is that better? How much flow do you think will come out of the single Nitro prop mod?
3. I think his dimensions are: 96Lx36Wx48H (or something like that). I will definitely do a double prop setup for him, and I guess I'll stick with 900s, but how many/what kind of placement do you think I should do. I was thinking of doing 4 (one in each corner) facing the center of the tank, but that might make a weird current when they all meet in the middle...any thoughts?

2. Once again all my talk about flow is completely unscientific and just my best guess. Having said that, my best guess would be somewhere around 1000-1200gph. As for placement, that depends on a lot of variables, like how your tank is aquascaped. I say, play with them and see.
3. Same answer I guess. One in each corner pointed somewhat randomly across the tank might be interesting to try.

Possibly... But I can tell you that I have my MJ400's running in my tank for about 6 months now and they're still as strong as ever.
In fact I think someone tried testing it out with a kill-o-watt meter and found out that the MJ actually uses less electricity with the mod versus its original design.
Besides the MJ's are cheap like areze pointed out previously. Even if I end up having replace the motor once a year (and I don't see that I will have to at the rate these MJ400's are performing), I'm still way a head versus spending the money on a Tunze.
D.
I would estimate the total cost of everything to be around anywhere from $20 to $40 depending on which MJ version and material you choose to use. Some propellers cost more but perform better for example, also PVC pipe also costs more than say a PVC adapter or coupling, etc...
Also keep in mind that you will probably have more than enough parts leftover to make several mods.

there is resistance on the coils that are in the powerhead body and turn the magnet.
like everything else, for every reaction there is an opposite reaction.
so as you put resistance on the magnets spin motion the coil gets resistance to the current. over time this resistance will wear the coil out.
but I believe in this case, and perhaps its proven by the power meter, the propelor is just a more efficient means of pushing water vs an impeller. the reason you dont see propellors in pumps is because it has essentially no pressure to it. I believe there is such a thing as a screw pump however, which actually has a ton of pressure.

Fitting 2" PVC. From the Motor Housing start with 1.5" PVC 1" then a 2"x1.5" reducer then a 1.5" section of 2" PVC. PVC Glue together before slotting. I know we have these in Black in Wisconsin. To get a more random output try cuting down another 2"x1.5" reducer just past the taper. You'll be amazed at how this speads the flow out. I've been using a very similar design for the outflows from external pumps and getting great eductor effects.
I believe he's talking about using a flush bushing reducer. which all said and done with his lengths would put you at 3.25" long.
whatever the case, make sure your propellor sits as close to the cross bar as it can without hitting, and IMO Id make sure that the slots are entirely behind the prop.

Hi, I just wanted to say THANK YOU SO MUCH!... I will definatly be doing this to the JEBO instead on the Maxi's!!!
Im going to do that to one to start with... using 2inch black ABS PVC, and a duel Nitro propeller...
Got a Q though, do you still need the same things?
same sized Propellers, Carbon rods, Ridgid airline tubing? is everything else the exact same...
please elaborate on that for us please...
I really want to do this JEBO VS MJ because of my new tank, a 210gallon...
this would be worth it... I plan on, if this works and how much flow. using 2 on the 210.... and a few maxis IF NEEDED! HAAHAA
thanks so far!

Hey... I can't seem to find any test caps around my area. Instead of having to pay $5-10 in shiping for a <$1.00 item, I was wondering if somebody that does have them in their area would be nice enough to mail me one or two. I would paypal you whatever the cost and you just put the testcap(s) in an envelope and mail them to me. If anyone would like to help out, please PM me, thanks!

Well I had mine made by someone on here (who will go unamed unless he is interested in getting some good publicity, mainly had them made because I dont have any of the nec tools and a place to work), and they are incredible so clean and professional.
Only one complain definitely noisier then the SEIOs but for the $ and the fact that maxijets kill any TAMM product in Reliability (Insert explative in here over TAMM products and dang if I wasnt so afraid of getting sued by the company thanks to a law suit between a certain imfamous major supplier of pet supplies and a person who gave an OPINION on a company that was handing out extremely POOR service to so many I will not say what I truly want to about TAMM).
I can put up with the noise. They definitely kick out more flow then the SEIOS. Less energy consuming and bulky too.
