How to Fix the Air Pump of a Saltwater Aquarium How to Fix the Air Pump of a Saltwater Aquarium
Air pumps allow for proper gas exchange and water circulation in the saltwater aquarium. They are also used to power the sponge filters, the under-gravel filters, protein skimmers and corner box filters. Most of the time, they exhibit disturbing vibration noises caused by their movable parts and this is how to fix them.
Step 1: Remove the Air Pump
To establish the defects, remove the bottom part of the air pump using the screwdriver.
Step 2: Inspect the Movable Parts
The air pump has three movable parts, namely the diaphragm, the magnetic arm, and the valve block. Inspect them for the following defects:
- Diaphragm: It will be defective if it is loosely attached to the valve block.
- Magnetic arm: Its hitting on the sides of the case while swinging shows that it is defective.
- Valve block: It will be defective if it is wrongly seated in its slot.
Step 3: Correct the Defects
Attach the diaphragm tightly to the valve block using the screwdriver. Fix the magnetic arm in a way that it does not hit the sides of its case and clamp the valve block firmly in its slot.
Step 4: Reattach the Air Pump
Reattach the bottom of the air pump after fixing the above defects. Ensure that you do it firmly using the screws to curb further noise problems.
