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.
