The barrels in the back of the 6-IBC grow out tanks are 2-media filters, 1 lava rock filter and on the extreme left, the sump. Aeration is provided to each individual IBC. Since my heart surgery this grow out system is for sale.
The large 1,000 tanks in the back are not currently in use.
I have used IBCs for sale also.
Best Wishes,
