The Ultima II 1000 is designed for ponds up to 1000 gallons. The high flow rate allows you to circulate your pond once every hour, giving you the optimal turn over rate to keep your fish healthy and your pond clear.

The Ultima II is specifically engineered to meet the environmental demands of ponds. The lightweight media is designed for very high flow rates. There is a patent pending on the tubular media which has low head loss and a very high biofilm surface. The “Y” shape on the inside and wings on the outside affords a protective surface under backwashing and the patent pending backwash system will keep the media from clogging.
