I have a couple questions. I have a Marineland Emperor 400 and a Marineland Penguin 350 filter system on my 75 gallon tank. My questions are regarding cleaning and replacing the cartridges (the things with the blue fabric on one side)
1) When cleaning them, I pull them out and wash them in a bucket that is filled with water from the aquarium, is this correct?
2) How do I know that it is actually time to change them?
3) When I change them, since there is 4 of them, how should I change them? One at a time? Two at a time? Or all four?
4) If one or two at a time, how long should I wait before changing the rest?
Thanks everyone!!!
