AquaHolland Bio-Pellets – round shape for nitrate and phosphate reduction
These round Biopellets are sinking and must swirl gently in a fluid bed filter. It always takes a while for the effect of biopellets to be measurable, since the bacterial culture is slowly settling on the pellets.
These bio pellets are specially designed for aquarium use and suitable for freshwater, seawater and pond use.
