Hello, I am setting up a new 55gallon tank and want to use a sponge filter on it as I hear they are quieter. I have never used one. My questions are, do I need anything other than the filter and the air pump? Such as extra air hose, or any fittings/valves? Also, what size air pump do I need? Do I need one to match the size of my tank? Or is that not necessary? Anything else I need to know? This is for a community tank with tetras and guppies.
