I need urgent help! I recently got a new tank. Here's the name to the tank: It comes with a FLUVAL external canister filter. I believe it is a Fluval 305 or Fluval 306 external canister filter. Right now there is NO fish since the tank is fairly new. I know about cycling and the nitrogen cycle and was about to cycle it but I can't figure out how canister filters work and any procedures. I have never used them and always stick to my HOB or sponge ones so this is a first time for me. Any help would be appreciated from the very start. I need to know how to set it up, how to maintain it and all the necessary so that I can start cycling my tank. I am grateful for any help I can get.
