Red Sea Reef Wave 25 Service Pack
The wear-parts kit for a ReefWave 25 that's starting to sound tired. Genuine Red Sea service pack for the ReefWave 25 gyre pump, covering the parts that wear during normal running.
Key features
- Fits ReefWave 25 only – not compatible with the ReefWave 45, which uses a larger impeller assembly and its own service pack.
- Covers the wearing parts – the components that typically need replacing on a running gyre pump, including the impeller assembly and snail guard.
- Keeps flow and noise at spec – a worn impeller is the most common cause of a ReefWave running quieter or slower than it did new.

Compatibility
Fits the ReefWave 25 only. If you're not sure which pump you have, check the model printed on the powerhead itself – the 25 and 45 use different service kits and the parts are not interchangeable.
Care and maintenance
Replace the wear parts when flow noticeably drops or the pump becomes noisier than usual – Red Sea doesn't publish a fixed replacement interval, and actual wear depends on your system's bioload and how often the pump is cleaned.
Goes well with
Pairs with the Red Sea ReefWave 25 – buy this when you're maintaining a pump you already own rather than reaching for a full replacement.
Warranty and delivery
Sold as a genuine Red Sea spare part; not covered by a standalone warranty beyond your rights under Australian Consumer Law. Standard parcel freight.
Common questions
Will this fit my ReefWave 45?
No – the ReefWave 45 uses a larger impeller and its own service pack. Check the model on your pump before ordering.
What exactly is in the pack?
It covers the wearing parts for the pump's wet side, including the impeller assembly and snail guard. If you'd like to confirm exact contents against your pump's generation before fitting, our team can check that for you.
How do I know when I need this?
Reduced flow, a noisier pump than when new, or visible wear on the impeller are the usual signs.
