I have an aquaclear filter for my 20 gallon and I am going to be buying one today for my 55 gallon. I was wondering if I have to buy their carbon packs or if I can buy the media bags and lose carbon. Does that work for the aquaclear filters? If so which size bag do I buy? How often do I need to replace the bags. Also how often do I have to replace the sponges? Do they really need to be replaced every 2 weeks or is it one of those things where you can really use them until they start to fall apart.
Thanks!
Thanks!
