Fish Dying? Do This Before You Change More Water

If your fish are dying, gasping, or acting worse after a water change, do not drain the tank again until you know what changed. This video gives you the safer rescue order: increase oxygen, test ammonia and nitrite, check temperature, use dechlorinator, protect the filter bacteria, and then decide how much water to change. You will learn: why another large water change can sometimes make the emergency worse when 20-30%, 30-50%, or a larger controlled change may be justified why ammonia and nitrite should both be 0 ppm why oxygen helps while you correct the real water-quality problem how deep filter cleaning can damage the bacteria your aquarium needs what recovery should look like during the first hour, first day, and following week Emergency Water Change guide: https://dbcaquatics.com/emergency-wat...
