Mojo's cone skimmer build

mojo · Nov 4, 2009

I am pulling about 1000lph. I like not having the output go down rather than having the output t out the side.

rkaires · Nov 4, 2009

1000lph that's great! Are you using the large PPW? Do you notice a slight difference in performance when the impeller turns in one direction as apposed to the other? I noticed on my Mini Airstar there is a slight difference in one direction as apposed to the other witch surprised me because of the non directional volute design.

I have enough room in my sump for the Mojo Monster. :bigsmile:

Snapped this little shot for you all tonight. The skimmer is working amazing

reminds me of your atb skimmate picture

mojo · Nov 7, 2009

yea well its pretty much a ATB hybrid ya know. Its an ATB cone body and then i made the rest. Running just over 1000 lph.

Very nice job. Your cone is skimming like a champ!

rkaires · Nov 7, 2009

Mojo,

The neck diameter is 4" ID or OD?

Thanks,

Bob

mojo · Nov 7, 2009

its 4 In OD. IT is skimming really really well. It is probably one of the best skimmers I have used. I am not just trying to float my boat or anything. But its basically the ATB 840 with a few mods. MY bubble plate is a little different, thicker plate and not quite as tall and no skirt. my exit plumbing has the water going out and down like the bk minis. No elbow then a T. Just a T.
I like it.

WOW unbelievable.

rkaires · Nov 7, 2009

Your skimmate is nice and dark. Are you running it on your 57 rimless? How many inches of water are you running it in?

mojo · Nov 7, 2009

yeap 57g , it runs at a steady 7 inches

Mojo,

Where can you buy the cone from?

mojo · Nov 7, 2009

If Victor has any they are about $100 for the cone body.

Looks good Mojo. Have you messed around with building a volute for the sicce that has a tangent output? I'm curious if that would make much of a difference instead of straight out in the middle like they all are right now. And since you have so much free time....kidding.

mojo · Nov 9, 2009

lol, no i havent any stock left to build it. Just didnt feel like buy a couple feet to make one.

luke33 · Nov 9, 2009

I hear ya man. Would be interesting to see the difference though. Next time!

mojo · Nov 9, 2009

I did make a reducer for my pump. it was .68 inches. works really well. not as large as the k2 but bigger than most. allows a little more water. using it with the atb large wheel. pretty good balance

luke33 · Nov 9, 2009

Yea, the sicce is like an endless mod. I had some pulling 65scfh with some reducers i made, but when hooked up they die down to around 30scfh. I honestly thing 40-45scfh is going to be max. But dang, 40scfh at 21w......pretty tough to beat, no other pump is close.

Hey Mojo you ever and schematics drawn up? Or is there any way to take some pictures of the volute you made. looking to do one for my sicce pump and am baffles as to where to start.
