I’m at the aquatic plants nursery today. Planting in varying depths of water is a VERY different kettle of fish and I’m keen to hear the specialists’ advice. A natural swimming pool consists of deep water, shallow, and marginal zones. In each of these zones are carefully selected aquatic plants which help with the cleaning of the pool. These plants are bedded in gravel and other special aggregates. Water from the swimming area is pumped through these biological and botanical filters so that microorganisms and other small life forms become permanently embedded and help to clarify and purify the water. The basis of this biological cleaning process is the use of aquatic plants and helpful microbes in connection with a biological filtration and hydraulic system. By mechanically circulating the water using controlled, directed flow through the regeneration zones, impurities are broken down the way Nature intended without the use of harmful chemicals. The surface water is cleaned with the help of skimmers and overflow gutters.
So essentially, what we are creating is an organized pond. It isn’t a glorified carp pond that some natural swimming pond systems deliver: apart from a skimmer and mechanical water circulation, everything else here truly is ‘as Nature intended’.
