Ok so was told need to over filtrate my cichlid tank. I'm sure most people with Africans would agree this is the thing to do right? Over the past half year I realized that no matter how much filtration I have I will never get rid of nitrates unless I do more water changes. So since I now need to change 50 percent water once a week to keep my nitrates down to an acceptable range. Why then do I need to over filtrate my tank and how does it help? Also one of my filters broke down and was worried things were going to get bad in my tank. To my surprize I have been finding my numbers just as good with the less filtration, since I need to do water changes once a week anyway to keep nitrates down. Just thought I would ask what you think about over filtering your tank and the reason you are doing it or not? This has been a learning process for me as been told if I had extra filtration I could go longer between water changes.(I was all for less water changes. Now I feel not necessary to over filtrate. Any thoughts, maybe I'm wrong? Do I need to go out and get another filter?
