I turned my filters off like usual when I fed my fish. Unfortunately, this time I forgot to turn them back on until I got home later on. They were off for a total of 4 and a half hours. My question is will all of the bacteria on my bio wheel be dead and have to seed all over again? I'm using a marineland penguin 200 and an Aquaclear 70. The bio media in the ac
filter stayed submerged.
