Interestingly enough, you don’t need always plants in a swimpond. They do help the balance and make it look natural, but everything we need the pond to do can be controlled by the filtration. So having this worked out and fit correctly is very important in terms of the pond.
There are companies that do a heavy plant filtration scheme in their swim ponds. This is not a technique we believe gives the safest and best swim pond. By using the filtration it makes the pond safer to swim in as it removes more bacteria from the water.
There are sometimes some British native aquatic plants we do incorporate into our Swimpond plans, including Water Lilies.
