I recently upgraded my whole system! My turtles are so happy! My question is, I just got a fluval 304 filter, There is no mention in the handbook as to how often to change the media, or how often the tank should be cleaned. With my old set up, I was changing the entire tank 2 times a week! I purchased this filter to keep the water in better condition, but have no idea how long I can let it go. If anyone knows Please let me know. It has been a week already and my water is still crystal clear! Thanks!
