I made a mistake ordering this hose for my Fluval 306 but it is a smaller diameter hose for the 100 and 200 series. The rubber end that comes with connected to the canister fits the 300 series, but the open end is too thin for the 300 series rubber hose adapters that connect to the outlet. It's my fault for assuming all hoses are the same, but maybe this will save someone else from making the same mistake.
