With all the surface area but 25% less weight than lava rock and half the weight of gravel, expanded clay Bio-Rocks are the more stable, less abrasive alternative to heavyweight bio-media. Use 1 box of 0.5 cubic feet of Bio-Rocks per Media Bag.

Customize your FilterFalls with three-stage Matala Filter Kits. Coarse, medium and fine Matala filter mats reduce channeling, increase surface area and backwash more easily than standard filter mats. Add over 300 ft2 of additional Specific Surface Area per kit, up to 2 kits per FilterFalls.

When used with Matala Filter Kits, Atlantic’s professional Back Flush Kit virtually eliminates FilterFalls maintenance. Add a Back Flush Kit to FilterFalls for fast, convenient, powered backwashing to save you time, trouble and a whole lot of mess.
