So today after a water change, my filter in my 5 Gallon API Panaview Aquarium stopped working. I have mixed feelings about this: 1) It was the loudest, most annoying filter in the world. I had to put a sponge over the outflow because it was so rough and that seemed to make things worse. 2) Now my Betta has NO filter and the water is very still. I recently ordered a new one from Chewy and it most likely won't be here until next week. How can I switch out the filters without putting my poor fish in complete shock?
