I personally keep an air stone on all freshwater tanks. I have seen them save entire setups too many times to not use them. If the filter ever stops running and that is the only flow and aeration fish can start dying in as little as a few hours. An air stone alone can keep an entire tank going for a week or more.
Not everyone has battery air pumps or generators so what happens during a week long power outage due to a storm ?
