Hi! I just recently got a 60 gallon long aquarium. I am currently cycling it fishless with a piece of raw fish. My water has gotten very brown, it may be from decaying plant matter or driftwood. I'm thinking about doing a water change to help with the brown water, but I don't know if you can. I know this might seem like a silly question, but can you do water changes when you are cycling a tank? Any help would be appreciated!
