Hello! So earlier tonight doing some maintenance, unplugged filter (sunsun302, don't judge) in a 55gqllon tank once plugged back in it was simply dead, no flow, no power. I have 2 long air stones in the tank with a heater, all working fine. My last angel fish passed after 8years, hence water change. Question is how long can everything last in the tank (new filter arriving in 48hours) extermely low stock now .a couple tetras and croy cat fish. And will my biologic filter be okay(unsing matrix and bio balls planning to reuse in next filter) Thanks!
