Eric,

Thanks for the reply.

Could you try the octura 1435 with your 1200?

It is supposed to be about the best prop for the MJ 900, but should produce about the same flow with the MJ 1200.

Could save you from buying the new 900s.

Just a thought.

Has anyone else had good preformance with the octura 1435 and the MJ 1200 on a four foot tank?

1435 will work fine in the 1200 . . they both spin at the same rate . 1200 just has more torque. In fact i think you are better off using the 1200 with either prop. for the tiny amount of added power (maybe $0.50-$1 a month) the pump will be more reliable.

pump you use often comes down to what you already have lying around though.

Just the simple mod where you cut the nozzle off and drill some holes adds large amount of flow. I have three of those right now on a natural wave timer and the tank almost has to much flow (with a SCWD to) as the switching currents really are superior to any constant stream.

But I am planning on putting one with the stream mod for constant flow across the tank. Maybe I'll convert one of the others at the same time.

I like how the basic mod (cutting and drilling it) causes the switching action. But the stream mod could add the flow I need for some harder corals later on.

I've now got both pumps modded and it's nuts. I had to do some re-arranging of my LPS so they wouldn't get torn up. Now that they're not in the middle of the "water storm" they seem to be opening up better with the increased water movement. This should increase my succes at keeping SPS now... hopefully.

 

[Snarkys]

ya , long as they are not in the direct path of the water the lps should do fine : )

 

[RichConley]

Just for those of you who worry about LPS and flow,

See my sig below for the flow I have. Its over 100x, and I've got a very large bubble coral,a hammer, and a frogspawn, as well as blastos, and some chalices, and it doesnt bother any of them. Just dont stick them directly in front of any of these things.

 

[Snarkys]

ya all off these things sound like a ton of flow but the dispersal cone is so large that after a few inches you can hardly feel it.

Just finished MJ1200 with Dumas 3004 and it works great. Now I need to order some magnets.

Thanks everyone for all your help!

I made an acrylic bracket for mine, here's the link:

I agree. I made my MaxiJet 1200 with a Dumas 3004 prop, and it is putting out more flow than my Tunze 6060. And definitly more than my Seio 820 or 1100.

I let my tank fill with microbubbles so I could compare the flow patterns. It's amazing how powerfull it is.

I'm amazed MJ hasen't actually came out with this as a unit yet.

 

[cooper9177]

I have to try this mod

they would have to come up with a better stopper and there might be patent issues with tunze ?

 

[ERICinFL]

As long as MJ used the same, basic design as the mod, they shouldn't have any patent issues. It's pretty amazing how one or two modifications to a product can get around patents. Just look at Euro-Reef and ASM skimmers.

 

[Snarkys]

sometimes fighting the lawsuit isn't worth the estimated profits ?

tunze could also have expected this and patented a ton of similar designs.

I'm just guessing though.


if they were to sell a add on to a normal MJ they would have to make it so it was a bit more reliable than it currently is . i bet 5% of the people now have issues with the home made mod , that's completely unacceptable from a commercial standpoint.

After attempting a few I am curious how reliable these actually are. I can't get perfect startup 100% of the time. I am wondering if the carbon fiber shafts are more reliable due to less drag?

It basically turns it into a Tunze stream pump.

My friend modded his. It's an amazing amount of flow for such a little pump.

Minus the controllability and good looks.

what type did ya build ? what impeller build , got any pics ?

 

[imtheonlylp]

so is there an ideal overturn rate? for my 75g ive got about a 16x overturn rate...im sure i could adapt this mod to my aquaclear4000's which are now pushing 396gph (each..then i assume around 400gph for my return pump)...but i dont have any dead spots in the tank and the fishes arent getting blown around....just wondering if more water flow would make it harder for hair algae to grab hold and set roots...?
