This is a 500g bag of macroporous adsorbent resin sold for aquarium filter media. It is meant to pull dissolved organics, yellowing compounds and odors out of tank water and to slow the buildup of nutrients that feed green water. It is a consumable refill, not a filter: it goes into a mesh bag inside an existing filter or drip tray. It suits keepers of goldfish, cichlids and other heavy-waste tanks who want clearer water between changes. Against carbon it targets color and organics more than chlorine, and it is cheaper to run than a full chemical media stack, but it does nothing for mechanical debris and must be recharged or replaced once saturated.

This filtration resin is made from macroporous adsorbent resin and comes in a 500 g pack. It purifies aquarium water by adsorbing harmful substances. It also removes odor and yellow water, and it treats ammonia and nitrite in the water.
It reduces green water, helps limit algae growth and removes fishy odor. The material states that it extends the time between water changes.
Before use, put the protein cotton in a mesh bag and rinse it with water. Place the bag in the filter tank or in the filter bucket drip box, where water flows directly onto it. When the cotton is saturated, soak it in salt water for up to 8 hours. Then rinse it with water for 2 to 3 minutes.
