There is a rule that respects animal species in biological pools. Those who come by their own means have the right to stay and live in the new artificial ecosystem. This rule applies to dragonflies, newts, frogs and more, even to terrapins, as long as they are native species.<\/p>\n
There is an exception to this rule which applies to waterfowl such as ducks and geese. If these birds appear in a biological pool, we have to act with it as quickly as possible because unfortunately they are very polluting species and can spoil the water quality in the short term. Since they remain almost all day on the surface of the water, they naturally use it as a bathroom. As, because of this, there is a danger of contamination with salmonella, waterfowl are completely incompatible with the bathing use of the biological pool. Consequently it is totally unacceptable to tolerate waterfowl in a biological pool, even for a few days. The load produced by ducks is very high and every day of \u00a0presence of water birds that remain in the biological pool is too much.<\/p>\n
What is to be done in these cases? The human presence helps to ward off these species in general. If that wouldn’t help, it is possible to install a “duck-scar” equipment. Through a jet of water, caused by a movement sensor, they are removed from the site.<\/p>\n
I confess, the spontaneous presence of water birds can be an interesting experience in a biological pool. There are regular visits from the heron and the kingfisher to ours in autumn. Those species don’t dirty the water!<\/p>\n
Another unique experience was with a cormorant, which simply fell from the sky like a stone on a stormy day and a lot of sea turmoil, looking for calm waters. He dove in once, found nothing to eat, got out of the water to dry his wings on the wooden jetty, and left. Another rather strange observation, but without any negative impact on the water quality of our biological pool.<\/p>\n<\/div>\n<\/div>
