How to do Water Changes in Freshwater Tanks

a-change-water-pythonRegular water changes are an important part of keeping your fish healthy, colorful, and happy. Unlike dogs and cats, fish cannot escape their own waste products, and have no choice but to swim in them until you change the water in their tank. Even if the water looks clear, a little prodding of the gravel will reveal how much uneaten food, fish waste, and other contaminates are causing stress to your fish.


Why Change the Water?

Waste products build up in the form of phosphates and nitrates, making them vulnerable to illness and disease. Elevated nitrate levels inhibit growth of young fish and can impede normal adult fish reproduction. Regular water changes are the way to keep the levels of phosphates and nitrates low.


Additionally, trace minerals and elements in the water are important to the health and vigor of your fish. Over time, these elements become used up or filtered out, and the pH levels will drop if not replaced. Fresh water is like vitamins for your fish, and should be a part of your regularly scheduled aquarium maintenance.


How Often Should the Water be Changed?

The frequency with which you change the water will depend on varying factors, such as how heavily stocked your tank is, and the type of fish you have. Generally, weekly replacing 10% to 25% of the water in your aquarium will keep your fish happy and healthy and colorful.
