May I change my dam into a Piscina Biológica®?

Perhaps in more than 90% of cases this is not possible. The dams are located in places where rainwater accumulates and collects the maximum amount of rainwater. But Piscinas Biológicas® need to avoid any surface water tributaries. The water of the dams is turbid due to the mineral waterproofing (clay and clay). This turbidity of the water prevents a good development of underwater plants.
