His tank just cycled. All readings, ammonia, nitrite, and nitrates are at zero for 10 days. His last water change was a week ago. There are three large plants and 1 1/2" goldfish in a 16 gallon Biorb aquarium. There is no cloudiness in the water.
If there's no ammonia or cloudiness should I change the water? Also, if you think I should, how much of a water change should it be? 50%? 25%? I know that with goldfish it is routinely weekly at 50%.
For the future, can I rely on chemical readings, or just routinely change water?
