Pumice for Filtration. Pumice is a light siliceous vesicular volcanic rock. Our pumice is mined from a land based resource, within 50kms of Lake Taupo in the North Island of New Zealand, and it is characterized by its relative hardness and light weight in comparison to competing aggregates. The washing and screening of our pumice means that no "fine" particles are included.

Pumice (/ ˈ p ʌ m ɪ s /), called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. It is typically light colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker vesicle walls and being dark colored and denser.

Pumice in water filtration can be used in mono or multi media filters. Potable Water Filtration; pumice filtration media is widely used in multimedia filters to treat potable water intended for human consumption. All our pumice filtration media has British Standard approval (BS EN 12906-2005) and UK Drinking Water Inspectorate approval.

Pond Matrix is the same as Seachem Matrix, made by the same company, but packaged and sold in bulk. Look at that if you want to save a few bucks. The risk involved with a local pumice stone source is not worth the few bucks you may/may not save. But, your mileage may vary. Expand signature.

Pumice Aggregate. Pumice Aggregate is a low density highly vesicular, volcanic glass consisting mainly of silica SiO2. The high silica content (70% per g/100g) positively affects the quality of pumice increasing the hardness of the material and its resistance to chemical attack.

" As a filtration media, pumice is used as an aggressively-filtering alternative to sand (and other filtration media) for the treatment of municipal and industrial effluents. The low specific gravity and high porosity of pumice make it ideal for these applications and treatment processes. A growing body of research has shown pumice to be an ...
