• The refill kit contains 2 pieces of activated carbon bio pads and 4 pieces of white floss pads, which can be used for one year.
• Activated Carbon Sponge Bio Filter Pads: Different from other traditional biochemical sponge filter pads, these filter pads contain double-layer activated carbon, which can absorb impurities and odors in the water, reduce fishy odor and yellow water problems, and provide a safe and clean environment for fish. Individual sealed packaging ensures optimal use for a long time.
• White floss pads: Trap most visible debris particles without restricting water flow; Filter out fine particles providing crystal clear water.
• Maintenance of the filter pads: The Pads can be rinsed and used repeatedly. Rinse the pads every month, replace the White Floss Pads every 3 months, and replace the Activated Carbon Bio Filter Pads every 6 months.
