Venturi Aeration

[moose]

Ran across these pages and wonder if anyone had tried or was using a venturi to increase o2 levels in the fish tanks. As I am learning O2 levels are a major factor in growth rates and determine feeding rates to maximize growth.

Hi Moose.

I'm sure I just posted a reply to this??? but anyway. . .
I used the design from the 3rd Link you provided and it is working very successfully.

Same concept as the links you posted.

Thank you or your reply sorry I missed it before. Trying to design for tilapia raising with quickest growth. I have been reading http://www.cherrysnapper.com/downloads/HatcheryManual.pdf which gets into some detail about the interaction between o2 levels and the amount of feed that can be used per volume of biomass. Just trying to learn more. The guy who wrote that manual has a very interesting story http://www.cherrysnapper.com/downloads/mystory.pdf
