Jet

  Jet has created a very neat system from IBC’s with three blue barrels incorporated into the system.  This neat system is based on the Chift Pist principle with two 1000L IBC’s acting as fish tank. The water leaves the IBC’s via a fairly modified solids lift overflow, from here the water flows into a swirl separator made from a blue barrel. In the separator the heavy solid particles of fish poo and uneaten food drop to the base where they can be removed when required via a drain with a tap in the base. The cleaner water leaves this drum via a pipe near the surface in the middle of the barrel, then flows through two different types of biofilters.  Once the water has passed through the biofilters, it then continues to flow through to the growbeds where there is a tap on each bed to control how much water enters individual beds.

The growbeds are filled with a course rock media , each growbed is the base section of an IBC, there are five growbeds in total, that sit on come large timber beams supported off the ground by cinder blocks or large cement building blocks. Under the growbeds are three IBC tops which have been inverted and joined together to act as the sump for the system. The growbeds have been fitted with autosiphons to control their flooding and draining cycles.  From the sumps, the water is pumped back to the fish tank where the process starts all over again.

A few things that Jet has changed,

modified or added since building his system are a battery backup pump in case of power outages. The return to the fish tank is now inside the tank, he has added a second pump in the bottom of the moving bed biofilter which means he can bypass the growbeds at night when it’s cold, helping to keep up the heat in the fish tank. There are also a few more changes or planned changes, hopefully we might be able to cover these in the next edition.
