The filter's water return is gravity-fed. Water is pumped from the pond up to the filter and through it, then returns back to the pond by gravity. Therefore, it must be placed at the edge of the pond in a location higher than the water to be filtered. It also requires the purchase of a separate pond pump for operation.
It is easily maintained. Just open the lid to replace the brush, sponge, or filter media.
While this filter can handle a normal pond up to 1000 gallons, in situations of high fish volume or particularly sunny locations (which encourages the growth of algae), we recommend it for ponds up to 500 gallons only.
The Bio Pond Filter is designed to be unobtrusive and blend with the environment. It comes complete with the filter brush, filter sponge, and SUPRA Bio Media.
