Has anyone built a pond in your garden

Did some research on the internet and found that The most important plant for pond is Anacharis. This is an underwater plant that uses up the nutrients that would otherwise feed the algae. For ponds and water gardens under 25-sq. ft. use one bunch for every square foot of pond surface area. For ponds 25 to 100 sq. ft. use one bunch for every two square feet of surface area. For ponds 100 to 300 square feet use one bunch for every three-sq. ft. of surface area. Use one bunch for every four square feet for ponds over 400 square feet in size. If you are keeping koi then a smaller upper pool or plant protectors will be needed to keep them from eating the Anacharis.
