Backyard Aquaponics
A place to discuss aquaponics

I am starting a new IBC system it is going to have two 200 litre grow beds one large fish tank made from a IBC which will have about 700 litres in it and another IBC with about 500 Litres for the sump.

I am going to b growing barramundi in the main tank. I was wondering what I should put in the sump i was hoping for some type of crustacean like red claw, marron or yabbies. What would you guys suggest? And how many would fit in a 500 litre sump or should i just get some other fish to put in there?

This will my topic for this system from now on.

Ideally I wouldn't put anything in the sump other than the pump.

Also 400L of GBs is not much for a 700L tank.
