Product Details

This fibreglass swirl filter has a capacity of 750 litres and following the formula for efficient operation, it can process 2250 lph flow through.
It has a tapered bottom allowing easy drain of solids that are collected.
It is 1100mm (3'7") high and 1450mm (4'9")diameter.

This will then be suitable if growing fish such as Silver Perch, Jade Perch, Murray Cod, Tilapia, and Catfish in a fish tank of 3,375-litre capacity.
If growing out Trout, Salmon or Barramundi the max fish tank capacity will be 2,250 litres.

The inlet coming from the fish tank is arranged so as to promote a clockwise motion of the water entering the filter and the processed water is extracted from the top middle of the filter.

We can pre-drill the necessary holes ready for Uniseals.

Manufactured with care in Brisbane Australia.

Freight or delivery needs to be quoted. It is a bulky item.


A swirl filter or a settlement tank is used in Aquaponics to remove/collect particles of fish waste, other suspended matter and leftover or uneaten fish food. The clean water coming from the swirl filter/settlement tank then flows back to the fish tank via the sump. I prefer to call them a settlement tank which best describes the function of a swirl filter/settlement tank in an aquaponic system.

Clean water benefits the entire system, fish health and plant health.

Only in very small home aquaponic systems would you not have a dedicated filter of some sort and even then, we would have a media bed in a small home system that will, among other functions, act as a system filter.  

Typically you would position the swirl filter or settlement tank between the fish tank and the sump so that you collect the solids that are coming out of the fish tank and stop them from entering into the rest of the system.

This is not to assume that we're going to discard these wonderful sources of nutrients (fish waste).  We will periodically clean them from the bottom of the swirl filter or settlement tank, put them in a mineralisation tank and we will further process to release these locked-up nutrients and make them plant-ready for the Aquaponics system.

In a will design Aquaponics system you will have the water flowing from the sump to the fish tank then onto the swirl filter or settlement tank then back to the sump.

The rest of the system, raft beds and media beds will be obtaining their water from the sump in the same way from the pump in the sump distributed by the use of a  manifold which will split the flow of water and send it to the various parts of the Aquaponics system.
