Static Kaldnes K1 - Mick

EditRegion5

	This photo shows the three vortex chambers in the filter house. 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.

This website started with a booklet which I made up originally for the help of those members of the BKKS - South Wales Section who were intending to start building a koi pond, and as the website has expanded more information and articles from other people have been included. This is for general guidance only, and we do not take any responsibility for problems that might occur by following these ideas. It is important that you check out everything in your area, and check on local laws and rules that may apply.
