1. It is a good idea to perform a frequent water change and cleaning schedule.† Changing the water in your aquarium will keep it clean for the fish that live in the aquarium.† Keep a full stock of the water treatment chemicals you will need for this purpose.
2. It is a good idea to keep carbon on hand in case of emergencies.† Carbon can be used to soak up anything harmful that may be introduced into your aquarium.† So keeping an emergency stock can be a life saver.
3. When adding new species to your aquarium, you have to ease them in.† Adding too many fish too quickly can cause the ammonia and chemical levels to raise quickly.† Adding fish slowly gives your filter time to catch up.
