As disussed in the previous article, we will be using IBC Aquaponics for our Aquaponics system. We have separated one IBC to use as a fish tank, and the remaining two IBC's will be cut into 3 parts to use as growbeds and one part as a sump. Let's do the growbeds and the sump.
To start, let's separate the base, the cage and the plastic tanks from the remaining two IBC's. Use a battery drill along with T-30, T-35, T-40 driver security bits to remove the screws holding the cage to the IBC baseline. Depending on the IBC type, you can use an ordinary hex headed machine screws.
We can start to cut the cage and tanks to make the growbeds and sump. I would recommend laying the cage on its side to do the cuts. Because of its fast and clean cut, use thin abrasive cutting discs. If you notice sharp edges on the cage, use a sandpaper flap or a flat file.
In this IBC aquaponics design, the two plastic tanks will be cut to form 3 grow beds and one sump. The 375 mm (15'') piece from the first plastic tank will be a sump and the same cut piece from the second tank will be the rear grow bed.
For the sump piece, you should use the bottom part from the first tank, this way you will have the tap/the valve included. The upper part of the first IBC should form the second grow bed(the 350mm - 14" piece). Finally, the same cut piece from the second IBC tank will be used as a second front grow bed.
