how to build & construct a concrete koi pond and what kind of materials to use?

I have a 7ft by 8ft section that I want to build a concrete koi pond but being a first timer I just wanted to get the most advice possible. so far I have a dirt hole with some cynder bolcks around the outside. Also how easy is it to pack in concrete on a vertical wall with no kind of form to pour it in.

Thanks Kevin

I have only seen one pond made from concrete and that one was short lived. They ended up going to a liner. a pond that size would be easily done with a liner. Concrete will also turn green rather fast because of the algae.those cinder blocks would be great for the edging around the top of your pond. you will need something to hold down the liner if you decide to use one. and the blocks also act as a good back drop for any flowers or plants you put around the pond. Have fun and good luck!!!!

    First, don’t use concrete. The binders leach into the water and poison the fish. Use a rubber membrane instead. Use rocks to cover up the membrane and make sure you have a filter of some sort. Go to http://www.aquascapeinc.com/ for more info. The rocks actually help the ecosystem, so don’t leave them out.
