FilterBalls Minis™

Rated to 15 microns, FilterBalls Minis™ are for use in conjunction with all FilterBalls™ products when bed depth is ≤ 12” or when filter vessel is ≤ 12” diameter.

FilterBalls Minis™ are designed to be added to the mix to fill the void in spaces when the bed depth is 12″ or less to reduce or eliminate channeling, but can be used for any bed depth.  Minis are used in a ratio of 1:2 (1 lb minis to 2 Lbs regular).
