Pond descriptions

Craig's and Lisa's pond

The finished pond

A view of the finished pond

The pond took 40 hours to fill just below the water inlet and in this time I also made the deck board filter lids, which are heavy enough to stop the kids from lifting them up. I also built a gate between the last pergola post and the shed to restrict access for the children and make the garden as safe as possible.

 
A few new fish are added Once full I just couldn’t resist in buying some small fish 4-5” and placing them in there new home

The third filter bay These three photos show the filter bays.
First we have the vortex chamber with three brushes covering the outlet to the next chamber.
Above right we have the second bay with bagged Flocor, and to the left we have the third bay with Alphagrog and a fine filter mat on top.
   
Additional vegetable filter Side view of vegtable filter
The vegetable filters were made from central heating water storage tanks that cost around £8 each from B&Q. I had to buy four tank connectors and nine 90 degree elbows and one length of 3m pipe all of which cost about £20. I used a Y connector piece before the venturi water return to feed the filters and slowed the flow down by gluing venturi restrictors the wrong way inside the pipes. Inside the filters I have a layer of alphagrog and then 10cm deep of 20mm pebbles. In one I have norfolk reeds and in the other I have watercress which I am growing from seeds.

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.
