BADU KOI Gravel Filters

The BADU KOI Gravel Filter Range is specially designed for use in koi ponds, ornamental fish ponds, nurseries, and aquaculture systems where superior water clarity and biological stability are essential. Manufactured by Speck Pumps South Africa, these gravel filters offer effective mechanical and biological filtration in a single, easy-to-maintain unit — keeping your aquatic environment clean, oxygenated, and healthy for fish and plants.

Using a layered gravel bed as the primary filtration media, BADU KOI filters trap suspended solids while simultaneously encouraging beneficial bacteria growth for ammonia and nitrite breakdown. Equipped with side-mounted multiport valves for easy backwashing and rinsing, they are compatible with most pond pumps and UV clarifiers, making them a versatile choice for both residential and commercial pond systems.
