PUMICE

How Does Pumice Compare? Using pumice as a filtration media has application in mechanical tank systems, such as tank-type "sand" filtration systems that recycle produce wash waters, supply drip irrigation systems, livestock watering systems, and other uses that need clean, clear water. Pumice is an aggressive filter media, trapping contaminates both between particles and on the rough-edged, foamed glass surface. Because it differs in bulk density from sand media, it can be used in concert with sand in dual-media setups... Pumice also offers a variety of grade sizes, allowing the grower to customize the drainage rate to fit the crop. Adding smaller stones tightens the intra-media spaces and holds water longer between the foamy stones. Blending in smaller stones also provides more surface area to retain moisture and nutrients over a longer period of time for plant uptake.
