difference between eductors and penductors
what is the difference (if any) and which one is better. I have found premade penductors for an awsome price.

The diffuser cone on a penductor tends to be shorter and more flared than the diffuser cone on an eductor. This causes flow separation on the side of the diffuser and results in less mixing of the high-speed jet from the nozzle with water drawn into the eductor.
The result is that penductors tend to produce a much more narrow, high-speed jet and eductors produce a broader lower-speed jet.

so if i do 2 pendictors on a pcx55 then would it be better to point the nozzles at the wall of the tank and let it disperse the flow?

Here's how my eductors are set up...
Flow from each converge at a point near the front-center of the tank. The water then moves downward along the front glass, through that arch under the rocks then up the back channel between the overflows. Keeps the bottom of the tank swept clean.

what pump.. from what the guy at KTH sales told me the thread size is just size effects nothing with the penductor.. and he said to get the .300 orfice and then if you feel you need to drill it out then you can... better to start small and go up.. i have the female 3/4 .300 4 of them on an iwaki 100.. the female 3/4 is what you woudl want if you plan ot hook them to loc line

That's from me as a Linux user.
Now to the topic. I'm getting ready to use these in a liquid-cooling system for my computer. I'm just trying to work out how to go about it. I'm looking for units to create a small cooling tower.
