Are Water Changes Needed with Live Plants?

Live plants are a fantastic addition to any aquarium. They not only look great, but they also offer a range of benefits for your fish and other aquatic pets, including improving water quality and oxygenating the water. But, as with any form of aquatic life, they require proper care and attention. One of the key questions many people ask is whether or not water changes are needed with live plants. In this article, we’ll explore the answer to this question.

The Importance of Water Changes

Before we dive into the issue of water changes with live plants, it’s important to understand why water changes are necessary in an aquarium. In an enclosed environment like a fish tank, waste products (such as uneaten food, fish poop, and other decaying matter) can build up, leading to a rise in toxic compounds such as ammonia and nitrite. These compounds can be harmful or even fatal to fish, even in relatively small concentrations. Water changes help to remove these harmful compounds and keep your aquatic pets healthy.

Do Live Plants Change the Equation?

Now that we’ve established the importance of water changes, let’s consider whether or not live plants change the equation. The short answer is: yes, they do. Live plants offer a range of benefits for water quality, including absorbing excess nutrients and removing harmful compounds. They do this through a process called “photosynthesis,” in which they take in carbon dioxide and release oxygen, using energy from the sun. This not only helps to keep your aquarium water clean and clear, but it also provides a natural source of oxygen for your aquatic pets.

How Much Do Live Plants Affect Water Quality?

So, if live plants can help to improve water quality, does that mean you can skip water changes altogether? Unfortunately, the answer is no. While live plants can be tremendously beneficial for your aquarium, they are not a replacement for proper aquarium maintenance. While they do absorb excess nutrients and help to keep the water oxygenated, they do not remove all the harmful compounds that can build up in an enclosed environment. Over time, toxic compounds will continue to accumulate, even with the help of live plants, and can only be removed through water changes.

How Often Should You Do Water Changes?

So, how often should you do water changes in an aquarium with live plants? The answer to this question depends on a few factors, including the size of your aquarium, the number and size of your aquatic pets, and the amount of waste they produce. As a general rule, however, it’s recommended that you do a partial water change of around 10-20% every 1-2 weeks. This will help to keep your aquatic pets healthy and your aquarium looking its best.

Conclusion

In conclusion, live plants are a wonderful addition to any aquarium and can offer a range of benefits for your aquatic pets. However, they do not replace the need for proper aquarium maintenance, including regular water changes. By performing partial water changes every 1-2 weeks, you can help to ensure that your aquarium remains a healthy and thriving environment for your fish, plants, and other aquatic pets.
