Aqua One Advance 750 Complete Filter Media Service Kit

This exclusive service kit contains all the filter media required to clean and renew the Aqua One Advance 750 canister filter, including: 2. 401s Blue sponge pad, 1. 402s black sponge pad, 2. 401w polymer wool pads and a large 600g pack of Aqua One BioNoodles. Its an entirely fresh start with no waste and no left over pads you'll never use (except for a spare wool pad for your first clean out) If your aquarium is mature and well stocked its best to change the filter media slowly over a period of time rather than all at once.
