This is a set of an aquarium filter, air pump, and vinyl tubing. I'm also including fish food and dechlorinator. External filter: CHAKRA 600A, AC adapter power supply. I bought this for goldfish, but the goldfish passed away before I could use it... It's been stored personally, away from direct sunlight. Non-smoking environment, no pets. Please refrain from purchasing if you are overly concerned about details (><) Thank you for looking. #AquariumFilter #AirPump
