Pumped Drum Filter System or Gravity Drum Filter System?
Will the filter be located above or at the height of the water level? The answer to this is important, because the maximum flow rates of a filter also depend on its installation type and location. Filters that are operated with a pump are often above the water level. Filters that use gravity are placed at the height of the water level.
Pumped Drum Filter System
A pumped filter system uses a pump installed in the pond to actively pump the contaminated water into the drum filter system, where coarse and fine dirt particles are mechanically removed through the drum's sieve. The cleaned water then runs through biological filter stages and finally flows back into the pond.
Gravity Drum Filter System
A gravity filter system allows water to flow from the pond into the drum filter unit via bottom drains or skimmers, using natural water pressure (gravity), where it is first mechanically cleaned of debris. The pre-filtered water then passes through additional biological filtration stages, such as moving bed modules, before being pumped back into the pond.
“My client loves the clarity they get from the Filtoclear pressure filters, even with a high fish load. They appreciate the ability to pump water uphill from the Filtoclear and hide it seamlessly within the landscape. The efficiency of the Oase pumps and the straightforward installation process have been a huge hit with them. It's been a game-changer for their hobby.”

"After 14 years, I convinced an ecosystem pond client to upgrade to an Oase Filtration System. Now, his pond is aquarium-clear—so clear, he dropped $15K on Japanese koi! The right filtration changes everything."
