Harpsandfish Posted January 21, 2023 Share Posted January 21, 2023 Good morning! I have a very healthy planted community 20 high. The water parameters are very stable and my fish all seem happy and healthy. I have a HOB and have been using a Co-op nano airpump. It has run like a top for two years, but recently stopped. If I tapped it on the wall it’s hanging on it would start up again but only run a short time. I replaced it with a new one and it seemed fine but then the same thing happened after a day. I changed out the airstone and same thing. It’s plugged into a usb adapter that’s plugged into the same outlet as the light and heater and they are fine. Help! And thanks!

TheSwissAquarist Posted January 21, 2023 Share Posted January 21, 2023 Have you been using the same USB plug? It could be that Link to comment Share on other sites More sharing options...

Darax Posted January 21, 2023 Share Posted January 21, 2023 Could the tubing or interfaces like check valves be clogged? Link to comment Share on other sites More sharing options...

Help! Leave the sponge itself in the tank. Take the rest of it to somewhere that you can take photos of everything please. There's a few reasons stuff like this happens and so we have to look into a few things. Question, does the air stone itself work alone without the sponge filter?

Harpsandfish Posted January 21, 2023 Author Share Posted January 21, 2023 The airline is separate from the filter. Link to comment Share on other sites More sharing options...

Does the air pump work if you set it up just to power an air stone in the tank? 1 Link to comment Share on other sites More sharing options...

nabokovfan87 Posted January 23, 2023 Share Posted January 23, 2023 Disassemble the sponge filter, take some photos of everything, check for fod/flack and make sure the air pathway isn't obstructed on the green plastic. There could be some calcium you might need to chip off or a piece of plastic from manufacturing causing some issues for you. Hopefully we can get it figured out. 1 Link to comment Share on other sites More sharing options...
