DIY "Stream" Style Pump

you beat me too it again i was jsut abou to post to tell you how i kept that from happening but YET AGAIN you have found a better way :)

I used the end of a writing pen (it fit right over it) but your idea is much easer to reproduce :)
 
It's running like a champ! I'm gonna let it run overnight and I'll see if it's shorted out and killed everything in the morning... ha

I'm gonna work on getting more intake for it tomorrow, even though I feel it is probably more than enough already.

Should I double up on the propellers?? Got one more handy - came in a 2 pack.
 
I think it would put to much drag on the motor... i had tried a racing boat prop when i first started and i guess it was to powerfull it would stop the pump sometimes...

How did you mount it in the tank? I dont know if you saw my box;s i made? Ied like to see how you mounted it.
 
I just used the suction cups it came with and mounted it sideways for now in my 70 gallon rubbermaid stock tank sump. I will probably create something out of acrylic to hang it with later.
 
Well, I just added a second prop and it is absolutely crazy! It is helping a lot. It could be that my props are a little smaller than most, but this thing is going great!

Gotta increase the intakes or even them out somehow...

Nice photoshop.

:)

FWIW - I wouldn't call this a DIY stream but rather a DIY reeftek. Most of what the stream is about isn't the mechanics of the pump.
 
MAN O MAN!!!! I setup mine now with the duel prop so they look like a corkscrew not inline like your photoshop photo :) and WOW very nice :). I set it up either way took pictures and a video and I believe the corkscrew is the best... I will post videos later so you guys can tell me which you think is best.

I also put PVC primer all over my intake and i have instant coralline algae covered intakes rather than a big white ugly thing. ALSO rather than 4 bars going across the 1 1/2" endcap I made it with 3 its still strong and i figure it has less resistance.

ALSO I dropped a 1/4" nylon washer down the shaft of the maxi jet that the mag portion rides on rather than the MH housing and now it starts up on its own every time :)

Haha I knew that would come up :P I dont think ited work I had to shave alittle off the leading edge of the 2 prop system to get it to work :) It so strong it was stoping the prop... Now we need a stronger powerhead to modify.

great work Niko, So for the corkscrew prop, you turned the second prop around?
Click to expand...

No, if he did that he would have them working against each other.

Niko just put them so they were end to end so to speak - like a "corkscrew".
 
thats correct just end to end and the blades line up to form the cork screw looking thing...

Reefwerkes how did you do yours?
