- Clogged airstones usually cause airflow loss. They become blocked as algae, floating debris, and mineral deposits accumulate in the pores over time. If you notice a diminished airflow, blow through the airstone yourself. If this is difficult, replace the airstone.
- Worn diaphragms or other rubber parts can also diminish airflow.
- Clean the outside of the pump with a damp cloth and mild detergent.
- Pump mechanism never needs oil.
Basic Installation: Place the Whisper Air Pump on a surface lower than the water level of the terrarium. To avoid damage for accidentally spilled water, do not place the pump directly below the terrarium. Use a check-valve between the pump and the terrarium. It helps stop water from siphoning into your air pump in case of an electrical power failure or when removing filters from terrariums.
Above-Tank Installation: Place the Whisper Air Pump on a shelf at least 12 inch higher than the water level of the terrarium, but not directly above the terrarium. NOTE: The shelf should have a raised edge to prevent the pump from sliding off.
Custom Installation: Use a Whisper Air Pump with 2 ports for alternate installation. NOTE: Use a Tee connector with your 2-port Air Pump for applications that require only one source of air. Air-control valves create multiple air sources. Use the valves to route the air from the Whisper Air Pump to different tanks, filters, air stones or air-operated ornaments. Adjust the air-control valves to regulate air supplied to tanks, filters, air stones and air-controlled ornaments. On 3-way valves, Knob 1 regulates airflow to Nozzle 3, and air flows through Outlet 2 unimpeded. Use end caps at the end of the line.

Wonderful!
By alexa on Feb 6, 2021
I have 2 of these pumps now, and I love them. They are so quiet it's wonderful! I use them to power the sponge filters in all 3 of my fish tanks! (I have 2 bettas in 10 gallon tanks. I have 1 pump powering the filters in both tanks.) I did get a dud, but chewy was happy to replace it for me! The first one I got made an awful grinding / rattling noise. I tried to get it to stop by moving it, and I slapped it a few times. After that it quieted down for a bit but not long. The replacement is perfect and silent! The tank this is on is in my bedroom, so being quiet is very important. Can't have anything messing up the calming sound of the moving water when trying to sleep!

Proper pump
By Ferrell on Feb 6, 2021
I’ve had the 40 running on my basement tank for over a year, NO Issues! Would buy these pumps for all my tanks! Could be a little quieter however, it’s noise comes from vibration due to Design. I placed mine on top of a piece of 1” filter foam and it almost completely silenced the unit. If used properly, these pumps will last many years. Many people complain about faulty units but I’m sure they are either trying to push to much air through to small bubblers causing back pressure on the diaphragm & motor. Sure there is always a lemon in the bunch but all in all, for the price this is a great pump.

Not my idea of “whisper”
By Michelle on Feb 16, 2021
This product is FAR from quiet. It rattles horribly. I have had this product prior and it was a quiet one. This one not so much. We have tried different tubing switching Ts and removing. No combinations seem to make it consistently quiet.

Good air pump
By Sheryl on Apr 15, 2021
Good air pump. Installed in back of the tank and tubing easily put into the tank. Does not come with the tubing!!!!

Super Pump
By Kenny on Mar 1, 2021
Hey, I got the 30-60 Gallon unit. I used it with a Penn-Plax 10" airstone and it works great. I attached an airline at each end of the stone.

Quiet and convenient
By Dana on Mar 2, 2021
Very quiet, and conveniently comes with a check valve and a control valve to adjust the flow. Perfect for running a sponge filter in a betta tank.

Whisper pump
By Whisper on Feb 24, 2021
I recently purchased 2 Tetra Whisper pumps and they really are quiet. My previous 2 pumps lasted 6 years so I would recommend them

operation report
By attheirbeckon on Jan 3, 2021
This pump was an easy hookup. I like the fact it came with a backflow valve. My unit is set on a carpet piece on top of our file cabinet, so the pump sits behind it. Out of site out of mind and quiet.

Died after 18 months, Tetra support offensively bad
By Chicago on Sep 25, 2020
Tetra had me open the unit to inspect the diaphragms, which looked fine, then had nothing else to say. I discovered the comments on Youtube videos about these pumps are full of people complaining about the communication they received from Scott Bonomo, the same awful person I had the misfortune to try to communicate with. I will never buy another Tetra product. I approached Chewy for help but got the cold shoulder.
