There are so many things to think about when you are looking at a container imbalance. The first thing that you need to realize is that the water chemistry of the tank or aquarium is the most important part of it. All of your fish need water and all of your plants and trees need water. If you do not have the correct water chemistry, no matter what you put in the water will be worthless.
It will also be worthless for the fish if they do not have access to food. This is where you may start to see some of the imbalance beginning. If you have too many algae or other plants with low saturation levels, then this is where you will need to go and get the right amount of light and nutrients to balance everything out. If the nutrients and light levels are too low, this imbalance will continue to get worse until you can figure something out.
You also have to keep the temperature of the water high enough for the fish to survive. When the temperature gets too low, this can cause problems with the growth of your fish. One of the biggest causes of a container imbalance is when the fish get stressed out or stressed over the lack of food. If you are constantly changing the foods that you give your fish, you are going to be running into trouble soon. Make sure that you keep the temperatures of the water high enough for your fish to survive as well.
