The slots on the acrylic tank would be awesome. I'm going to have to go with bulkheads though my tanks glass.
I dont know about efficient. Easier to make...Deffinately. This wont be your average diy project.
Those bearings look sweet and should work fine. Now for the auger. If the pitch is say 2" the diameter is 5.9 and the shaft running through it is 1" Thats going to move how much water at 1 revolution? Once thats figured out we'll know what kind of rpm range we'll need for the motor to get the gph we want.

You can't get it going too fast or it will cavitate like the prop on a boat.
try one of those squirl can paint mixers (the plastic ones with the stainless steel shafts) on a drill motor (or something similar)
Actually, I have no idea what this post is about, I just wanted to say something.

Basically you will move:
((((5.9/2)*3.14159266)*2)-(((1/2)*3.14159266*2))/231)=.2299 gallons per revolution.
So...if you want to move say 25 gallons in a 6 second burst you would need to turn:
25/.2299=108.74 revolutions in 6 seconds or have a motor that will turn about 1087 RPM.

Hey Anthony, I called mark he's picking up the 180 and bringing me the 210 lol 
Hmmm I see the pitch is going to have to be much more agressive to get the flow we need...

well now were talking speakeraddict.
humboldt reefer, in my specs for the auger i called out a 12" OD on the tube that the auger will go into not a 6" one, so, if possible it would be nice to use that size, i can probably work out a deal to get some 12" or similar size SDR pipe from HCSD, i know a guy who works high up there, that will save on the cost of acrylic tube. now for the motor issue, this will be the biggest problem, but i will do some leg work to find out a source and price
it's starting to look like this DIY project will really work
oh yeah, H reefer, how you gonna get your 210 drilled for 6" bulks i think K7N glass will be in over their heads, j/k but it would be nice to see the look on their faces when you ask them to drill for a 6" bulk, personally i think you would be better off using 2 or 3 3" bulks because you could use standard abs fittings and save some money
and just think, if we can get the kind of flow we are looking at getting then this would be really the only means or circulation you would want, maybe a few seios or something on a chauvet timer like i use, set mine to switch at 3min from channel to channel, and even if the dc motor draws 500w you would be way way way more efficient then a big closed loop that would give you gph in the 20-30K range

Damn the only way i could do it would be with a smaller auger. We dont have a cnc lathe at work and the manual ones wont turn 12" material.

whats the largest bar stock you can chuck up then
then i can redraw to fit the auger
we now know what values to plug into speakeraddicts math to find out how many rpms and what not.
speakeraddict:
does your equation have any factor in it for the pitch of the auger, because i see thatthat would be a big factor into how many times it would have to spin to move the auger's length of water volume

Might have to go with two or even three augers then.
You guys by the way "ROCK" It is about time someone thinks outside the box for saltwater reef tank water flow.
I believe we are wasting time, energy and money on powerheads and whimpy pumps to move water.
Lets break out the big boys and be efficient at the same time

I'm not sure but I think its an 8" chuck. I'll check tomarow. I just did a quick search I think speaker addict may have missed part of the formula. It's pie*r squared*length. So say an 8" auger with a 2" pitch and 1 inch shaft would be.
3.1416*4 squared * 2 = 315.8288
3.1416*.5 squared * 2 = 4.9348
315.8288
- 4.9348
310.8942/231
1.3459 gallons per revolution
so at 800 rpms thats 1076.72 gpm
or 64,603.2 gallons per hour
:eek1: We might have to slow it down...........Nah

well even if it takes a good sized motor, i would use one for that kinda flow, and my tank is acrylic so i could glue it on there. but formy tank i would use a slightly smaller one and it would have to be plumbed through the back using something like a faux back and slot method but still keeping the auger asm. outside the display tank.

crap I forgot... Order of operations... exponents first. So the above math is wrong.
It would end up being about 22,287gph I thought those numbers seemed kind of high

Now that will move a little more than you want... @ 187.5 gp 20 seconds.... @1500 RPM's
Yet it doesn't come in a gas engine.. DAMN!

I think one of us needs to contact a CNC shop and find out how much we can have 4 and 6" bulkhead fittings made for.
I am not willing to expirement with over $500 in just two bulkhead fittings.

I know of a guy with a cnc lathe, I'll see what I can find out. I'm sure we could get some made a hell of a lot cheaper than 290 apiece. Were supposed to be getting one at work but who knows when that will be.
I read a post by a guy named Allen on aqualink about 7 years ago; He took a saltwater trolling motor, put PVC pipe around the prop with screens at both ends and then built a simple circuit to reverse direction on it every so many seconds. This sat in his 240g tank behind the rock structure.
His account of the water motion was reminescent of diving trips to the reef.
If I recall he said he had to replace it after two years; which at the price of the unit, was cheaper at the time than the replacement cost of metal halide bulbs every year.
Just a thought...
