IOAOI PuriResin Aquarium Filter Media, Organic Filtration Resin, for Freshwater and Saltwater Fish Tank, Removes Driftwood Tannins, 100 ml

About this item

• FUNCTION. This filter media is an organic filtration resin which is developed to remove nitrogenous compounds and waste produced by fish, corals, and even plants, making your water crystal clear.
• SPECIALTY. This special filtering material is not a mixture of ion exchangers or adsorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water.
• ADVANTAGE. Being both spherical and macroreticular, it has microscopic pores that increase its contactable surface area to many times than most spherical resin.
• REGENERATION. Color changes from light yellow to dark brown, even black while it adsorbs the waste. Once it is exhausted, it can be regenerated with a solution of bleach and water.
• CAUTION. Some slime coat products may permanently foul it and makes regeneration difficult. Do not reuse it if odor of bleach/chlorine is detectable. To ensure safety, submerge it in small quantity of water and test for chlorine please.
• Age Range Description: All Stages. Rinse before use.
