In biological pools the water temperature is slowly rising, but the aquatic plants still need a few days with more than 16ºC water temperature to launch new shoots. At the beginning of the season, to ensure that algae do not proliferate, collective cooperation and ecological interrelations between organisms constitute the complex process of biological [...]
