This is a description of the filter system written by Mick himself.
The filters are a vortex system which I cobbled together myself. I have a 4" inlet and 4" slide valve before the 1st vortex which has a sort of home made easy containing static k1. The 2nd vortex has 100 litres of fluidised k1 with 40 litres of air, and in the last chamber has Japanese matting which I am thinking of changing to more static k1 for polishing the water and taking those final fines and muck out of the water. |

This photo shows the three vortex chambers in the filter house. It is in a bit of a state at the moment as it is being rebuilt.
My static K1 chamber works for me and does a great job of trapping the fines and knocking the waste to the bottom of the vortex for flushing.I wish I had 3foot vortexs instead of the 2 foot ones I have then I could make one out of the inside of a washing machine.

This photo shows how the water has to pass through the k1 when re-filled and running. I clean it by shutting off the flow from the pond and leaving the water in the vortex then agitating the k1 with a cane then flush to waste. I then re-open the slide valve and flush the bottom drain line, and then I re-flush and re-start the system. You could add an airline into the buckets for cleaning instead of using the cane.

| My first attempt just had the buckets drilled, but these were clogging with blanket weed so I cut some of the bucket away and covered with the mesh. The photo on the right shows the water flushed out. The pipe in the centre is to stop the water back syphoning from the middle chamber as I don't have slide valves between them. |

| The middle vortex chamber chamber has 100 litres fluidised Kaldnes K1, and 40 litres of air is supplied by a 40l/min Airtech air pump. |

The last chamber has a Japanese matting cartridge. On top of this is a sheet of Japanese matting for polishing.
