Keeping a swimming pond clean and free of algae with chlorine has the advantage that your pond water will remain almost completely clear throughout the season. Only little effort is required, and the costs for 10 to 20 kg of chlorine are also reasonable, but nature falls by the wayside.

Chlorine has both advantages and disadvantages

In traditional swimming pools, the purity and clarity of the pool water is achieved through sometimes significant doses of chlorine and other chemicals. Bacteria and mainly algae are kept in check by the toxic components contained in this chemical disinfectant solution and have no chance of spreading significantly, which, however, is not good for human skin at all.

Swimming ponds have self-cleaning powers

And they are all the stronger in the natural pool, the better the biological balance can come into its own. The physical separation of bathing and regeneration areas by a wall in the pool breaks down excess nutrients in a completely natural way, prevents algae formation and even eliminates pathogens on its own. Nevertheless, clean water is the be-all and end-all for a naturally healthy swimming pond, so that every owner has to make their own decision in favor of the chemical or biological variant.

The disinfecting effect of chlorine

The germicidal effect, also known as cold burn, is chemically based on the oxidation between chlorine molecules and the organic impurities in the pond water that cannot be removed by filters. A distinction is made between inorganic water care products, which release their chlorine components immediately in the pond, and those on an organic basis, which only take effect when the chlorine content in the pool falls below a certain level. Available as granules or in tablet form, chlorine is added to the pond water via adjustable or automatic dosing systems. Relatively new on the market are electrolysis systems that are installed near the pool and produce chlorine independently.

Regulation of chlorine demand and alternatives

The chlorine levels in the water must be checked and readjusted regularly using special measuring instruments, test strips or commercially available hand-held measuring devices. Of course, the general chlorine tolerance of the bathers also plays an important role, since it is much harder to endure the chlorine water with red eyes or burning skin. Otherwise, apart from the natural state of the pool, there are the following alternatives to a swimming pond with chlorine:

  • disinfection with active oxygen;
  • cleaning of the swimming pond water with ozone, which, following disinfection, returns to the form of the original oxygen molecules;

tips

Thanks to its integrated filter and the aquatic plants in the regeneration area, an artificially created swimming pond also has an excellent biological cleaning system that is completely maintenance-free and comparatively inexpensive. The decision in favor of a classic and natural look should therefore not be difficult.
