I juts bought one of these yesturday for my 55 gallon and it works great I have one question however. The filters it comes with also the only ones you can buy have carbon in the back of them and the way its set up you can't remove the carbon. My question is in the back of the filters theres small holes would I be able to take a knife or a pair of scissors and make a big hole to get the carbon out. Its the only way I can think of to get the carbon out seeing how they don't sell filters wothout carbon, or atleast from what I have seen. Thnaks for your replies!
