Awesome, I'll check this out this evening. Any idea what gph it is giving you?

Haha, that would be quite easy then. Literally any motor would work, choose a brushless motor that can work under load which spins at ~2000rpm, and pick a couple diametrically poled >5 pound magnets and wha-la, you've got a working powerhead that pushes >2000gph and could work to probably 2" thick tank
If only sound isnt an issue... I guess to some the amount of sound I'm talking about here isnt too big of a deal. (the worst brushless motor spinning at 2000rpm pushing 1500gph will at most deal out 45db.... which is a loud computer fan)
Thanks Chichas! You wouldnt believe the amount of time put into such a small project. Its pretty comparable to my actual railgun/coilgun projects. Mainly due to the lack of planning on this project, haha!
Thanks Rob! Definitely take a look later tonight or tomorrow morning when I get a video posted.
Now that you mention it, when this DIY pump is put next to my k-nano, I'd really have to say that it pushes a good 300-350gph at 90% power. It definitely moves more water than the k-nano at 240gph.
I'm currently running it at ~40% power just because with it, I get this turbulence zone right in the middle front of the tank which is perfect because a lot of my corals are placed front and center, which gives them very random water movement.
I'll post a how to thread sometime this week or next. I'll try to cover a wide range of things including... (1) nano tank [50-300gph], quiet. (2) Medium/Large tank [600-2000gph], quiet. (3) Medium/Large tank [600-2000gph] loud. This thread will take me some time though.
My next goal will be to make a 555 chip of some sorts to turn my powerhead on/off every 3 seconds or something along those lines.
Price rundown on finished non programmable, but controllable DIY exterior motor driven magnetic pump:
Motor: 5$ (Probably could get cheaper. Its 3$ online shipped)
Speed controller: 5$
Magnets: 7.50$ (Probably could get cheaper, ~4$ online shipped)
Prop: 4$
Prop shaft: 3$
12vdc power supply: 5$ (I got mine for free because I have so many old cell phones and one of them had a 12v @ 1A charger)
Cost using online vendors: 24$
Cost using local vendors: 30$
