Was thinking of building one of these IBC aquaponic sytems. What sort of air pump would I need in this? Assuming there'd be about 200 gallons of water in it.
Oh, didn't know of this method until now. Well that helps alot lol. Thanks mang
So that just requires a water pump then right? Could I get my air flow as well as my flood and drain to the plant bed off just one pump?
not that adnon but out of curiosity why does everyone recommend venturi?
Your going to wear the pump out faster and an airpump is also a pretty cheap way to circulate water and add air.
Thanks for the link mang :^)
Yeah this'll be my first system, won't need it til' spring so if I can sell it at a profit I'll do that and just build another system. Just trying to make it simple keeping any customers in mind, so being able to run the system off of one water pump would be ideal, while still being able to fulfill the air needs to a variety of fish.
it depends on the species and number of fish.
>not all fish like high energy water movement
>many fish need much oxygen
and warmer water holds less oxygen
and smaller oxygen bubbles are better:
stay longer in water,
better oxygentransferrate because of volume
at least one venturi and two airpumps
Hey, guys. I'm building a fairly large aquaponics system. At the moment I have everything I need, but if I expand what is the cheapest possible growbed per square foot? My current plywood boxes with plastic liner is nearly $5 per sqr/ft.
I did not say that a venturi effects the amount of water a pump moves. Maybe I wasn't that clear but I'm not sure how you inferred that from my sentence.
From personal experience I think converting a water pump into a venturi shortens the life of the water pump. I don't know how or why but I will continue to believe this. Maybe its back pressure on the pump.
I think for less electrical cost the average air pump moves more water in terms of overall circulation while adding air at the same time.
