Water Filtration Pebbles #5/#10/#15 20KG/Sack for FRP Multimedia Aquarium

Available Sizes: Pebbles#5 Pebbles#10 Pebbles#15 -Sand and gravel make good water filters because they form permeable layers. When comparing the rate of flow between different filters, it is generally found that the tighter the spaces in the filter, the slower the flow of water. These small spaces cause tiny dirt particles to be trapped in the filter media.   -Pebbles are used in Water Treatment Filtration Media with Silica Sand, Anthracite, Activated Carbon, Birm, Pumice and Garnet in potable water treatment, RO reverse Osmosis treatment plant, surface water treatment, swimming pool water treatment, and waste water treatment also in conventional water treatment filters. We ensure that all products are inspected before packing and shipping. *We do not have control over delivery once the courier pick up the order *Delivery of an order may vary depending on courier led time. *Only the courier is responsible during delivery period. *Please check your order right away once you receive our package. *If there are issue.please feel free to sent us a message..
