Filter Gravel

Filter Gravel-1
Filter gravel does not filter water directly, but acts as a supporting layer, preventing filter sand from entering into a water collecting system. It is also very important to conduct backwashing evenly. To make best use of the effect of filter media, it is important to use filter gravel of carefully selected quality. For our filter gravel, almost all of the flat gravel, cracked fragile gravel, seashells, etc. are removed by hand. We thus always provide high-quality rounded gravel.
