Hi All! Just wondering if anyone has every created a minimal water change system? And if so how often you do water changes? I have a 28 gal biocube with the sump off the back. I've considered adding a 5 gal refugium with cheato, pods, sand, rumble rock. How much more time will I have between water changes if I do this (on average). Currently I change out my water (5 gallons) every week and everything has been well. The tank has been up a year and fully cycled. I have a mandarin, 2 pipe fish, 2 clown and a diamond watchman in the tank. It also has a with few sponges growing I didn't add (they just started growing off live rock), I've added many mushrooms, duncan, leathers, candycane and trumpet corals. Thanks for your advise! I know no one can "tell" me exactly when I would need to cycle it as every tank is different but curious what others have observed?
