MaxiJet sureflow 1600gph?

Not open for further replies.
i havent noticed an noise out of my sureflow, and i just installed it last night. i guess if i had a bigger tank i would change the props but being that my tank is only 36" long , i think this is enough flow for a tank with mainly LPS and just a few SPS
 
so now that you guys have tried a bunch of different mods and variations, i am pretty confused but what would you suggest to add for flow for 150g? i have a CLS with return manifold on the top but it obviously needs alot more as i am just getting into SPS.
right now its mostly LPS and softies but left the top half of my rocks pretty barren for SPS.

anyway which would be the best flow? quietest and cheapest to do?
i already have 2 MJ 900s i want to use.
i expect i can order those 80 lbs disc magnets and glue directly to the MJ's. please help clarify?!
 
Actually, the ECO Mod uses a counter screw stop on the end of the impellor. When the impellor comes forward it engages it and nothing touches the prop. You can see in the pic of my prop I tried to mimic it by trimming with a razor blade to match what comes with the ECO mod. How does the Sureflow incorporate this? Does the tab hit the prop?

I also tried both ways of doing the mod but like the impellor the way I showed.

AquaPython - I have run one MJ Mod with the Dumas prop in a <a href="http://www.advancedaquarist.com/2007/1/aafeature" target="_blank">gyre flow</a> style 24/7 for over a year along with a CL and have had great results.

well my tank is already set up so the only sort of gyre i can do is just have the 2 mjs push parallel to each other so it makes a circuit. however even that is imperfect in my tank as it has the single overflow in the back middle.
is the MJ mod still available? i thought it was off the market? i understood my only 2 options now are the ECO-mod and the Sure flow. and then possibly using that Dumas prop on them.
 
AquaPython - Yes that would be the only option now as they are not available any longer. dhnguyen is running the Dumas in the SureFlow with no problems. I have only tried the ECO so far and my SureFlow should arrive today or tomorrow.

Oh, as far as noise goes. I’m thinking that the shroud on the ECO Mod with the Dumas prop is restricting the flow to the prop and causing it to vibrate. It is dead silent in the old MJ Mod shroud.

I thought about mount two of these with included props, apposed to each other, and use my AC jr. to run one at a time for say 15 minutes then switch. Anyone doing something like this with the new shrouds/mods?

Well imo, you'd be fine with the stock impeller's from eco or sureflow. If you are going to order the 80lb mags then you could go the cheaper route and get two eco's from marine depot for 14.99 a pop. I am running one with an 80lb mag directly on the back and it is just as silent as teh sureflow. One in each opposite corner of your tank should be fine. If you have a DSB like me, your not going to be able to get away with 5000-6000gph without a sandstorm. I have 4000gph and my sand is not moving, but i am doing it very careful. My old hydor 4 was not a good pump for my tank.
 
ok but with the magnets on the ecos, you basically can only have it point directly perpendicular to the pane it is on, with no angles, right?

i have 2-3 " sand bed, not a DSB.

if i put one in the front corner then the rocks are not getting directly blasted. if thats ok, idk?
but the second one would be along the back pane and would get chopped in half and stopped from my center overflow column. so one back corner/ 25% of the tank wont be getting the rapid flow.
 
Well if you ever want to mod it to use a larger propeller you might be better off with the sureflow kit since it uses a stopper tab. Not sure how you would incorporate the "counter screw" stopper onto another propeller.

I’ll try and get some better pictures tonight. Basically I just used an exacto knife and trimmed the front of the Dumas prop/impellor to match the ECO Mod. It was pretty easy.

Received my SureFlow today and here are some comparison pictures with the ECO Mod.

The ECO on top and the SureFlows on the bottom. The SureFlows shroud is shorter and wider.

Here is a pic of the two props. SureFlow on the left and dhnguyen you can see the "counter screw" stopper on the ECO on the right.

IMHO the ECO is better crafted. It feels like it is made with better material and the injection molding is slightly better than the SureFlow. But no doubt about it the SureFlow with the included prop puts out more flow and to me it was quieter. With the Dumas it rocks! I will be using the SureFlow housing and it comes with a great adjustable mount. Video to follow.

Hmm while that counter screw stopper may work with the Dumas prop, I think it might be a problem if a higher pitched propeller likean Octura is used. The prop blades on the higher pitched props are pretty far forward. Your prop will hit the center brace before it hits the counter screw stopper. Note that there is a bit of extra plastic at the end of the eco mod prop to accommodate the screw, you won't have that in other propellers.

Neat design though.
 
can you show me how your prop looks with the dumas prop on it, and maybe what you did to remove the stock prop off of the sure flow? Jmait if you think the eco mod is better have you tried to put a duams prop on it? if so what were your results with it keep the pics comming thanks
 
frezel - The prop/impellor is from the original dhnguyen MJ Mod. It works in all of the shrouds.

Go to page 7 and read fwd for a comparison of all three. The ECO is better made but I like the SureFlow better because of the flow and the mount. This is my opinion and both are really great mods for the MJ pump.

as we all know the maxije mod page is huge 100+ pages big, i have the dumas 3004 prop but is that metal rod the one that came with the maxi jet or is it bought and the clear tubing as well. did you buy these pieces from reefchilli, or lfs? if so do you recall the sizes and or page that shows that construction, (length etc) thanks again, and ill stop being a pain in the arse
 
USC-fan â€"œ Thanks! You will not be disappointed with the ECO Mod.

frezel - The clear tubing is standard airline tubing I bought at the LFS. It is the same that MJMods.com sold. I basically cut the plastic from the magnet and inserted the tube with a little superglue. The metal rod in that picture is from the ECO Mod with end caps. Maybe dhnguyen can post the sizes as I have forgotten them. He explains the other more common way of doing the mod <a href="http://www.reefcentral.com/forums/showthread.php?s=&postid=10892516#post10892516" target="_blank">here</a>. I would not mod a new prop from the SureFlow kit as I think you will be pleased with the flow as is.

Can anyone confirm that the sureflow does put out 1600gph? I just installed 1 on a mj900 and 1 on a mj1200. I was really expecting a lot more. With 3200gph in my 75g, I was expecting sand storms and unhappy softies. But, if it is actually 3200gph, then that's perfect because the flow isn't too harsh on my softies/LPS. I'll try to get some videos up soon.
