What is Amazon Sword?

Amazon Sword (Echinodorus amazonicus) is an aquatic plant that is widely used in aquariums. It is native to the Amazon River basin in South America and is one of the most popular plants in the aquarium hobby. Its lush green foliage is a wonderful addition to any aquarium and it is relatively easy to care for. Amazon Sword plants have wide, long, and thick leaves and can grow to be quite large, up to 18 inches tall. They are also known for their ability to tolerate a wide range of water conditions, making them a great choice for beginner aquarists.

What is Hard Water?

Hard water is water that contains a high concentration of minerals, such as calcium and magnesium. It is usually caused by the natural leaching of minerals from the soil into the water supply. Hard water can cause problems with plumbing systems and can make soaps and detergents less effective. Hard water can also cause staining on sinks and tubs, and can leave a white, chalky residue on dishes. In aquariums, hard water can be damaging to fish and plants, as it can make the water too alkaline.

Do Amazon Sword Like Hard Water?

The short answer is yes. Amazon Sword plants are generally quite tolerant of a wide range of water conditions, including hard water. In fact, most aquarists find that Amazon Swords actually prefer harder water, as it helps to keep the pH of the water at a consistent level. Hard water also helps to provide the plant with the minerals and nutrients that it needs to thrive. The only downside to having hard water is that it can cause a buildup of scale on the leaves of the Amazon Sword, which can detract from its appearance.

How to Care for Amazon Sword in Hard Water?

When keeping Amazon Sword in hard water, it is important to make sure that the pH of the water is stable. This can be done by regularly testing the water and adjusting the pH accordingly. It is also important to ensure that the aquarium is well-maintained and has plenty of oxygen. Amazon Sword plants do best in an aquarium with a temperature between 70-82 degrees Fahrenheit and a pH of 6.5-7.5. Regular water changes will also help to keep the water clean and free of debris.


Amazon Sword plants are quite tolerant of hard water and can be a great addition to an aquarium with a high mineral content.
