Just got a fish aquarium from a friend of my mine. 48 gallons with some great freshwater fish that they have had for over two years. I love everything about the setup except for one thing, the filter! It's a hang on the back whisper and it's so loud. The tank is located right outside our bedroom so it kept me up all night. Annnnyway bought an Ehiem 2217 a canister filter because it was said to be quiet and powerful. Now after reading I have scared myself with the whole bacteria stuff. I really don't want to run both as it's just too loud to deal with. What is the best way to seed the bacteria without the other one running? Can I utilize the inserts from the whisper in the canister? If so how? It has the white bag of charcoal and the wirey course sponge thing. Thanks in advance for any help.
