In fact, it is not, It is informative...
1. I never said a 900 GPH pump is better.
1A. there is about 1-2 PSI on my pump, and there are 0 leaks, even without using any clamps
1B. Theres 1-2 PSI resistance
2. Thats why im going to downvolt... And I already read Una's post.
3. They must have a Variable dimmer thing or something I can use somewhere...We did go to the moon, I think they might have a dimmer or the like to control motors
3A. You skipped 3A dumbass
3B. Its a $45 pump so its not really industrial, Its just big and strong.
...Anyways, I never said this is a good Idea, But I will make it work. And If I cant Ill head over to K-Mart and get a small cheap marine pump.

Well, just to let you know, the "dum***s" remark was uncalled for, but anyways.
I will give you that the idea of running a large pump, and running it underspec, is a perfectly valid idea, from a reliability point of view.
On the other hand, as almost everyone else has pointed out, you are going to come across some difficulties.
If it's any help, you could try a diode, to clip the sine wave of the AC, but I'm not sure how you'd wire that up. It's a very cheap setup, and it's not a flexible one, as you won't be able to change the voltage, unless you swap diodes, but it will work. If you want a variable supply, then that a whole different ballgame.
The fundamental problem that we have with your idea, is that it's not practical, in terms of all the adjustments of the power for the pump. You have to remember that your pump will probably require 250W (at max voltage) of power which, very much like a Power Supply, will cost around $40. (but hey, a couple of diodes, rated properly, would probably cost less than $5). And as we've pointed out, it may not work at all.
But again, I will give you credit for coming up with something that would be more reliable than anything else any of us are using.
Personally, I'd rather spend 24$ on a couple of RIO pumps, or for reliability's sake, just fork out the $60 for the Eheim, which will fit nicely in my case.
