For the fellow fish lovers and aquarium owners, this guide can be used to fix an Air Tech 2K0 Aquarium Pump. Ideally, this pump is used in small ten gallon or less tanks and is great for Betta fish that do not like strong currents.
Over time, these air pumps suffer from wear and tear from use. The rubber diaphragm found inside that vibrates and compresses air through the tubing line can break down, ultimately causing the absence of bubbles in the tank even though the pump itself is still running. If your pump is brand new, check the assembly of the tubing to ensure airflow is not being hindered or blocked. If that is not the case, or your pump is just old and worn in, this guide might be useful in restoring the bubbles back to your tank.
Before beginning any work on the pump, make sure it is disconnected from the power source.

-
Examine the diaphragm for damage.
-
Here, you can see a hole in the diaphragm that needs to be repaired.
-
-
-
Using the Gorilla Glue, coat the diaphragm on both the inside and outside of the damaged area to ensure adhesion.
-
-
-
Allow the glue to dry thoroughly before reassembling the air pump.
-
-
-
From here, follow Step 4 in reverse to reassemble the diaphragm and its attached metal piece:
-
Insert the screw (1.25mm x 8mm) through the hole of the diaphragm.
-
Place the metal piece flush against the back of the diaphragm, making sure to line up the screw with the hole.
-
Finally, screw the washer back on to ensure a secure fit between all the pieces.
-
-
-
Place the reassembled diaphragm back into the slot you initially removed it from.
-
-
-
Place the cover back on the air pump, lining up the holes for the three screws (13mm x 2.9mm).
