Your aquarium pump is the heart of your desktop reef tank. It provides the water movement your corals and livestock rely on while powering your filtration system. Over time, detritus build up inside the pump, reducing flow and making it work harder than necessary.
The good news? Cleaning your pump only takes a few minutes and is only needed every 6–8 weeks.
What You'll Need
Hot RODI water
Small plastic container
Cotton swabs
A small towel or workspace
Tip: Never use soap or household cleaners on aquarium equipment. Hot RODI water is all you need for routine cleaning.
Step 1: Remove the Pump
Turn off your pump and remove it from the aquarium. Place the pump into a container of hot RODI water for a few seconds. This helps soften detritus buildup, making everything much easier to clean.
Step 2: Remove the Front Grate
Take off the front grate of the pump to expose the pump cover. Once accessible, remove the cover so you can reach the impeller inside.
Step 3: Clean the Pump Cover
Using a cotton swab, gently clean the inside of the pump cover. This area commonly collects debris that can restrict water flow over time.
Step 4: Remove and Clean the Impeller
Carefully pull the impeller out of the pump body. A clean impeller spins more freely, allowing the pump to run quieter and more efficiently.
Step 5: Clean the Pump Body
With the impeller removed, you can now clean the inside of the pump. Don't forget to also clean the return tube and nozzle, as buildup here can also reduce flow.
Step 6: Reassemble the Pump
Once everything is clean, you can go ahead and reassemble your pump. It is now ready to go back into the aquarium.
How Often Should You Clean Your Pump?
We recommend cleaning your pump every 6–8 weeks as part of your regular maintenance routine.
Unlike weekly water changes, pump cleaning isn't something you'll do often, which makes it easy to forget. Setting a reminder on your phone or marking it on your maintenance checklist can help keep your system running at its best.
Why This Matters
A dirty pump doesn't just reduce water flow, it can affect your entire aquarium. Keeping your pump clean helps maintain proper circulation, improves filtration, reduces unnecessary wear, and ensures your desktop aquarium continues running efficiently for years to come. Spending just a few minutes every couple of months can make a noticeable difference in the health and stability of your reef.
