In addition to bringing connection with nature, lower water consumption and preservation of plant species are some of the advantages of the model.

“The biological pool offers mental health benefits similar to ‘forest bathing’, an oriental medicine practice that has been recommended by psychologists around the world. In addition to being refreshing, the pools have this introspective character. Snorkeling in a biological pool has a relaxing effect that is good for the mind and body”, explains biologist Rafael Catarino, owner of Clímax Ambiental. 
Biological pools have the power to surprise and bring life to the outdoor area , much more than a conventional pool. But this is far from being the only advantage of investing in the structure. 
Contrary to the use of chlorine, biological pools use microorganisms to purify the water . The presence of fish contributes to this function, as they help control algae and mosquito larvae, which creates a biological flow – which is where the name comes from. Ozone is the only element added to water. With a cleaning power far superior to that of chlorine, it does not have adverse effects that could compromise human health, such as respiratory allergies or skin problems. 
To ensure this balance, it is important to have professional support for the creation and maintenance of the pool. Catarino emphasizes that a series of precautions are necessary to ensure self-regulation , from the creation of the biological filtration system to the control of ozone so as not to affect the health of the fish. When choosing fish, the biologist warns about different temperatures . Carp are recommended for regions with mild climates, but for warmer regions, such as the Brazilian northeast, it is worth looking for native species .
