Six Reasons Why You Should Never Neglect Changing Water In Your Aquarium Tank

If you want to always see your beautiful fish swimming in your aquarium tank happily and healthily, you should never neglect the important task of cleaning your aquarium tank and making regular water changes. The following are the main reasons why water changes in your aquarium tank are extremely important:

  • pH control – pH stands for Potential Hydrogen. It is actually the concentration of hydrogen ions present in your aquarium tank, and in case you didn’t know, hydrogen ion concentration refers to acidity of the water in the tank. As fish live in the water, performing all their biological activities, the pH value is bound to change. The best way to ensure that the pH values remain conducive for the health of your fish is to change the water often. (Note that betta fish prefer a pH level of around 7.0).
  • Kh control – For the scientifically inclined people, Kh is the carbonate hardness. Simply speaking, it is ability of water to buffer, which means, maintain a particular optimum level of the acids and bases in it. Changes occur in the fish tank over time due to the inclusion of chemicals produced from biological activity. That is one reason why the water has to be periodically changed.
  • Controlling nitrate levels – Ideally a freshwater aquarium should have nitrate levels under 20-30 parts per million. Fish excretion is in the form of ammonia, which increases the nitrate level of the tank. There are protein skimmers available that can help to keep the nitrate levels to optimal levels within the tank. But these skimmers will not be able to remove the organic debris that collects in the tank from time to time. That is the reason why complete water changes become necessary. In fact, aquarium sellers do stress upon nitrate level maintenance as the most important reason for making periodical water changes.

  • Detoxifying the aquariums – Dead aquatic organisms, byproducts of metabolic activities in the fish and other aquarium residents and the excretion products of your fish will definitely introduce some toxic products in your aquarium tank. Some toxic materials can also enter from the external environment, such as when things drop into your tank or when some microorganisms enter through the air. They could play havoc with the health of your delicate betta fish. Unfortunately, you cannot effectively monitor such toxic intrusions. The best way to be proactive is regular water changes.
  • Cleaning aquarium accessories – If you have live elements in your aquarium tank such as live sand, live rock, sponges, bio balls, etc. it is best to provide them with clean water of aquarium standard to filter out the wastes that they produce from time to time.
  • Controlling algal growth – Algae are microscopic plants that grow in all types of aquatic environment. They grow faster in aquariums because the water there is stagnant and favorable for their growth. However, algae can pollute the water in the closed environment to drastic levels, which could also mean health problems to your fish. Not only that, algae will compete with the fish for the resources available in your aquarium. If you change the water in your aquarium regularly, you are also removing the algae that have grown in them.
