Pond for koi and goldfish
external aquariums for koi carp and goldfish. They require adequate volume, powerful filtration and protection from predators.
Detailed explanation
The minimum volume for koi is 5000 litres. The minimum depth 80-100 cm in Italy.
Filtration must be robust: mechanical filter, biological filter, and optionally UV. Predators (especially herons) are the number one enemy.
The plants must be protected in baskets because the koi dig and uproot everything. The diet is seasonal: proteins in summer, wheat germ in autumn/spring, nothing below 8-10 degrees.
Ventilation is critical in summer and winter under ice.
