A place to discuss aquaponics

Hi,
I am based in Dubai, UAE. At present I have a IBC fish tank of karp for small setup. I am planning to have another setup by June end. The fish tank which we have in mind is of 1000 litres and to put Tilapia

Like to request advice on how many Tilapia fingerlings can I introduce initially
Please advice
Thanks

How much GB area and volume do you have?

Hi,
Thanks for the mail.
My grow bed I have made using IBC tank, the surface area for the plant to grow is (1.2M x 1.2M) and the volume of the pebbles in each grow bed in 200 Liters , like this I would like to introduce 3 of the grow bed.
We will be following the CHOP system
One Fish tank of 1000 Liters
three grow bed (each of 200 liters of pebbles, grow area =1.2 m2
One Sump (700 litres)
Thanks
Joseph John

That works out at only about 14cm deep pebbles- ideally you'd have about twice that depth.

As it is with 3 of those GBs, it will probably safely support about 20 fish maximum.
