Aquarium Filter Replacement Impellers

Choosing the Correct Replacement Impeller

Read the filter identification label and product compatibility details. Similar-looking impellers can differ in diameter, magnet size, shaft or mounting.

• Match the complete filter model.
• Check what parts are included.
• Inspect the impeller well and shaft.
• Disconnect power before removal.

Signs an Impeller Needs Attention

Noise, difficult starting or reduced flow may point to debris, wear or damage, but blocked media, plumbing or intake parts can produce similar symptoms.

Cleaning Before Replacement

Many flow problems improve after careful cleaning of the impeller and well. Follow the filter manual and avoid damaging ceramic shafts or rubber supports.

Model-Specific Fit

A part for one Tidal size should not be assumed to fit another. Use the compatibility stated on the replacement listing.

Replacing an Aquarium Filter Impeller

Unplug the filter, isolate water as required and follow the manufacturer’s disassembly sequence. Keep small shafts, bushes and covers in the correct orientation.

After reassembly, prime the filter if required and check for quiet operation, normal flow and leaks before leaving it unattended.
