Description
The Inland Seas Nu-Clear Model 547 is perfect for applications where a biological filter outside the tank or pond is desired, or when existing biological filtration is not sufficient.
The filter contains three gallons of premium 1” Bio Balls with a combined surface area of over 60 sq. ft. on a high flow grid.
This is enough biological filtration for systems up to 180 gallons. Although this filter resists trapping, we suggest using it after a Model 522 or Model 533 mechanical filter.
