Aquarium Advice FINatic
I bought a second AquaClear filter to replace my Whisper 20 because it was noisy thinking it would be as silent as my first AquaClear but it makes the same noise that my Whisper did! I googled it and applied Vaseline to the impeller shaft and it was quiet for a few hours but it's making noise again. I know it's not the lid rattling because I have a bottle sitting on top of it so it doesn't rattle. Should I apply MORE Vaseline to the impeller or is there another simple fix I don't know about?
