hi this will be my first aquaponic atempt i am excited but also concerned i thought i would show what i have done to start with .
i purchased a 1000 letre ibc and have cut the top off to make it a 800 letre tank and the choped top will be the first grow bed i also have a 1750 l/h pump
and got my hands on some scoria for the grow bed . i have done some calculations and i am not sure if they are correct but i thing the tank should drop by aprox 65 letres when the bed is full of water . dose this mean i have a 800 letre tank or a 725 letre ? will upload pics wheni figure out how.
