## Long description

Replacement impeller compatible with the Tetra Tetratec EX 800 Plus aquarium filter, designed to restore and maintain the pump function of the EX 800 Plus unit. This spare rotor assembly returns the rotating element and magnet coupling to proper working condition, ensuring steady water circulation and reliable mechanical filtration in freshwater aquaria.
Advantages
The impeller is made to match the dimensions and rotation characteristics required by the EX 800 Plus, helping to reduce vibration and operating noise when installed correctly. Installing a new rotor can recover original flow rates and improve filter efficiency without replacing the entire filter. The spare design makes routine maintenance straightforward and supports longer service life of the pump assembly.
Suitable for
Restoring pump performance in Tetra Tetratec EX 800 Plus filters
Routine maintenance and part replacement to reduce noise
Improving water circulation and mechanical filtration in freshwater tanks
Key specifications
Function: rotating impeller (rotor) for aquarium filter pump
Compatibility: designed for Tetra Tetratec EX 800 Plus filter units
Material: wear-resistant plastic and magnet assembly for rotor operation
Operation: restores magnetic coupling and impeller rotation to maintain flow
Intended environment: freshwater aquarium use
How to use
Before installation, disconnect the filter from power and remove it from the aquarium. Open the filter housing following the Tetra EX 800 Plus service instructions, extract the old impeller and clean the compartment of sediment and debris. Insert the replacement impeller into the rotor chamber with correct orientation so the magnet coupling aligns with the motor shaft, then reassemble the housing and return the filter to the aquarium. Reconnect power and verify smooth rotation and expected flow; if necessary, re-seat the impeller and repeat cleaning to remove any remaining obstruction.
Usage recommendations
Inspect and clean the impeller and chamber regularly (monthly or as needed) to prevent buildup that reduces performance. Handle the rotor and magnet assembly carefully to avoid dropping or bending parts, and use only compatible replacement parts to maintain filter reliability and safe operation in freshwater aquaria.
