I've had my tank for a little over a month now and besides my own mistakes as a 'newbie' and an outbreak of ick it's been going fairly well. Recently I've noticed my tank is murky and I'm not sure why. I did about a 25% water change in hopes it would clear up but its not much better. I've also changed the carbon and cleaned out the filter in general. I'm I missing something? Any body have any advice on what I should do?
