Our water filter gravel and support pebble has the same properties as filter sand only difference being its shape which is highly spherical therefore promoting good flow and even distribution in support beds. Support gravel, the lower strata of a filter bed, acts to support the filter media.. Correct gradation and sizing must be calculated to properly support the filter media To insure a clean, quality product, our filter gravels are double washed to remove all clay, shale and inorganic impurities. High purity, consistent quality gravel makes this media ideal for filtration.
