Evan Posted April 30, 2021 Share Posted April 30, 2021 I've been running an Aqua Top 100 air pump since January. Last night it started making a new noise that sounds kind of like a fluttering or warbling sound. Has anyone else encountered this? Could the air pump be defective? Thanks.

Colu Posted April 30, 2021 Share Posted April 30, 2021 It could be a problem with the diaphragm Link to comment Share on other sites More sharing options...
Cys aquatics Posted April 30, 2021 Share Posted April 30, 2021 i dont have an idea abou this since i only have run aqueon and fluval air pumps but i will tag @Fish Folk, @Cory, @Streetwise, Link to comment Share on other sites More sharing options...
Administrators Cory Posted April 30, 2021 Administrators Share Posted April 30, 2021 Have you tried adjusting the knob? Air pumps wear, and if it's at max you might turn it down just a smidge and it'll be quiet again. Link to comment Share on other sites More sharing options...
Evan Posted May 1, 2021 Author Share Posted May 1, 2021 Thanks all. I will try fiddling with the knob and the air stones too. Link to comment Share on other sites More sharing options...
Evan Posted May 1, 2021 Author Share Posted May 1, 2021 LOL I just now saw today’s video on the More Aquarium Co-Op YouTube channel. Very timely! Not exactly my issue but still funny. Love Irene! 1 Link to comment Share on other sites More sharing options...
Evan Posted May 2, 2021 Author Share Posted May 2, 2021 Update: I turned the knob down a bit and loosened the air stones and the air pump is back to its normal sound. Thanks for the advice! Link to comment Share on other sites More sharing options...
KBOzzie59 Posted May 2, 2021 Share Posted May 2, 2021 Also, many pumps have a small felt filter over the intake. See if it is caked with dust and clean if it is. 1 Link to comment Share on other sites More sharing options...
KBOzzie59 Posted May 2, 2021 Share Posted May 2, 2021 (edited) As you can see this Tetra 100 filter is in need of a cleaning. A great time to check them is with each filter maintenance (or if the pump gets loud). edit The user manual will give direction on cleaning the filter if one is equipped. From the Tetra manual Care and Maintenance of your Tetra APS Air Pump Always disconnect the air pump from the power supply before carrying out any maintenance work on the unit. This unit does not require lubricating due to its low-maintenance design. The air filter (C) should be replaced periodically depending on the accumulation of dirt on the felt pad. Failure to replace a blocked air fi lter may result in decreased air fl ow from the unit. Clean the outside of the unit using a damp cloth and a mild detergent. Do not use abrasive or caustic cleaning agents when cleaning the unit. Never immerse the pump in water. @Cory @Irene Maybe a video or blog on this?

KBOzzie59 Posted May 2, 2021 Share Posted May 2, 2021 One more thing. This is why I use Tetra for my tanks that are not on my main air loop. I can get replacement parts. 1 Link to comment Share on other sites More sharing options...
