Foam stone is a unique, eco-friendly filter media, heated in excess of 900°C, creating a hypercannected glass cell structure. This produces media with a surface area at least 10 times greater than most ceramic filter medias. Furthermore, the weight is extremely low in comparison to other porous filter media.
Product Feature
The foam stone has a structure of interconnected porous cells Allows a huge biological surface area for the growth of beneficial bacteria Helps prevent pH drops. Eliminate ammonia and nitrite, minimize nitrate Suitable for multi-bay filters and trickle filters. Stabilize PH and GH consistency water chemistry Provides more healthy and stable water value Easy maintenance and Extra durable
Parameter
Foam stone is a porous and light vitreous acidic volcanic volcanic rock whose composition is equivalent to rhyo- lite. The surface of foam stone is rough, the bulk density of the particles is 450kg/m3, the bulk density is about 250kg/m3, the porosity is 71.8-81%, and the water absorption is 50-60%.
