The Beckett 900 GPH 84 Watt Submersible Pond, Waterfall, Stream, Water Garden Pump and Filter pumps up to 900 gallons per hour. It has a maximum lift of 13 feet. At 84 watts, the energy-efficient design pumps 800 gallons per hour at the height of 1 ft. The 900 GPH pump is ideal for creating cascading waterfalls up to 5 feet high or for a large sized pond up to 1800 gallons. This value-packed kit includes a pump, two foam filters, t-fitting, and adapters. The foam filters trap particles to prevent your pump from clogging, increasing the life of your pump. Foam filters also help to improve water clarity by creating the perfect home for beneficial bacteria to grow. Beneficial bacteria feed on the organic material in the water that passes through the filter to keep your water clean and clear. Clean your filter regularly by submerging it into a bucket half-filled with pond water, gently massage and squeeze the foam. This ensures that the beneficial bacteria remain in the foam filter. This pump is compatible with 1 in. ID tubing and has a 15-foot cord.
