How often should I change my fish tank water?
You should change 10-15% of the tank water once a week. Then once a month you should change 30% of the water. Be sure to use dechlorinated water, you can add a chlorine and ammonia neutraliser.
At the same time as you change the water, or at least every second time, you should test your water levels for ammonia, nitrate, nitrite, hardness, chlorine and pH levels.
