hey was wondering if i should replace my old ceramic white rings in my fluval canister filter, i got the fliter off of craigslist and im assuming she didnt clean it much, should i repalce all the media also?? its got carbon, sponges, white rings, some other stuff in bags. i already have 2 emp 400 on my 75 gallon tank, only using one right now, very low stock right now. but i still wanna use the canister. how should i set up its media keeping in mind im a cheapo

oh yeah its a fluval 204 thanks again guys..
