Aquarium Advice Addict
Haha I don't follow that rule at all. I just do good regular water changes. That is a good rule for a beginner until they are comfortable caring for fish.
IMO it's not even good for a beginner. What if that beginner wants to put a 10" fish in a 10 gallon tank. According to the inch per gallon rule that is ok. Most experienced aquarist will tell you that, that rule is a joke and everyone should forget about it.
