Bag of Gravel – 50 lbs.

Description

Support gravel for water filtration systems. This 50 lb bag is used as the lower support layer beneath filtration media in systems using carbon, pH neutralizer, Birm, Greensand, Greensand Plus, Katalox, Pyrolox, and Filter-Ag media. You only need about 16 pounds to line the bottom of each tank, so one bag can be used across multiple tanks.
