The age old question: How frequently to do PWCs? And how much can be safely changed at once?
I have a 55 gallon (which actually holds closer to 49 gallons) and I change 7-9 gallons every week; sometimes twice per week. My profile will give more details on my tank.
I have read and have always thought that changing too much at a time could cycle the tank. Now I'm reading that some change 50% up to nearly all of the water can be changed out safely. What's the popular opinion here?
