Water in the new container should not be changed within two months. During this period, fish adapt to unusual conditions. Residents of large aquariums are more difficult to adapt to the characteristics of the environment.
When the new capacity will be used already 2-3months, you should start to add a little more water. Substitution is subject to about 20% of the total fluid volume. It is necessary to perform this procedure every few weeks. Performing topping, you need to clean the glass, as well as remove all the debris that accumulates on the ground.
