The ProEco BF Series gravity flow filters are ideal for large ponds and water gardens. The Bio Flow gravity flow filters deliver crystal clear water with very low maintenance. A high volume of oxygen is introduced as the water enters the filter, which maximizes the biological filtration process. The foam filter pads create a healthy environment, which supports the beneficial bacteria that complete the biological filtration process and mechanically remove particulate.
