КАРПЫ КОИ В САДОВОМ ПРУДУ С ПЕСЧАНЫМ ФИЛЬТРОМ

A koi pond requires a powerful mechanical and biological filtration system. In my garden pond, I used a sand filter for mechanical filtration and an 800-liter barrel with 500 liters of floating biofilm. The pond has a capacity of 18 cubic meters, a 15 cubic meter/hour circulation pump with a prefilter, and a 75-watt UV filter.
