The quest for a perfect aquarium is a lifelong journey for many aquarists. One of the most crucial aspects of maintaining a healthy and thriving aquatic environment is controlling the water hardness. Water hardness, also known as general hardness (GH), is a measure of the concentration of dissolved minerals such as calcium and magnesium in the water. High water hardness can be detrimental to the health of fish and other aquatic organisms, leading to a range of problems including scale buildup, fin damage, and even death.
As an aquarist, it is essential to understand the importance of controlling water hardness and learn how to decrease it in your aquarium. In this article, we will delve into the world of water hardness and provide you with a comprehensive guide on how to decrease hardness in your aquarium.
Understanding Water Hardness
Water hardness is measured in degrees of German hardness (dGH), which is a scale that ranges from 0 to 32. The ideal water hardness for most aquarium fish is between 5-15 dGH. However, some fish species are more tolerant of high or low water hardness levels, so it is essential to research the specific needs of your fish before making any changes to your aquarium.
There are two main types of water hardness: temporary and permanent. Temporary hardness is caused by the presence of dissolved minerals such as calcium and magnesium, which can be removed through the use of water softeners or reverse osmosis systems. Permanent hardness, on the other hand, is caused by the presence of dissolved minerals such as iron and manganese, which can be more challenging to remove.
Causes of High Water Hardness
There are several causes of high water hardness in aquariums, including:
- Using tap water that is high in minerals
- Adding too many minerals to the water through the use of fertilizers or supplements
- Using a water conditioner that does not remove minerals effectively
- Not performing regular water changes
- Using a tank that is not designed for high water hardness
It is essential to identify the cause of high water hardness in your aquarium and take steps to address it in order to create a healthy and thriving environment for your fish.
Methods for Decreasing Water Hardness
There are several methods for decreasing water hardness in aquariums, including:
Water Changes
One of the most effective ways to decrease water hardness is through regular water changes. By replacing a portion of the tank water with fresh, dechlorinated water, you can help to dilute the concentration of minerals and reduce the overall water hardness.

When performing a water change, it is essential to use a water conditioner that removes minerals and other impurities from the water. This will help to ensure that the water is safe for your fish and other aquatic organisms.
Reverse Osmosis Systems
Reverse osmosis systems are a popular method for decreasing water hardness in aquariums. These systems use a semi-permeable membrane to remove impurities and minerals from the water, resulting in a lower water hardness level.
Reverse osmosis systems are available in a range of sizes and can be used to treat both small and large aquariums. However, they can be more expensive than other methods and may require regular maintenance to ensure optimal performance.
Water Softeners
Water softeners are another effective method for decreasing water hardness in aquariums. These systems use ion exchange technology to remove minerals and other impurities from the water, resulting in a lower water hardness level.
Water softeners are available in a range of sizes and can be used to treat both small and large aquariums. However, they can be more expensive than other methods and may require regular maintenance to ensure optimal performance.
Distilled Water
Distilled water is a pure form of water that has been filtered to remove impurities and minerals. It is a popular method for decreasing water hardness in aquariums, as it can be used to create a low-water hardness environment for sensitive fish species. (See Also: What Are Nitrites in Aquarium?

However, distilled water can be more expensive than other methods and may require regular maintenance to ensure optimal performance. Additionally, it is essential to use a water conditioner to remove impurities and minerals from the water before adding it to your aquarium.
Conclusion
Decreasing water hardness in aquariums is a crucial aspect of maintaining a healthy and thriving aquatic environment. By understanding the causes of high water hardness and using the methods outlined in this article, you can create a safe and healthy environment for your fish and other aquatic organisms.
Remember to always research the specific needs of your fish and other aquatic organisms before making any changes to your aquarium. With the right techniques and equipment, you can create a beautiful and thriving aquarium that will provide hours of enjoyment for years to come.

Frequently Asked Questions
Q: What is the ideal water hardness level for my aquarium?
A: The ideal water hardness level for your aquarium will depend on the specific needs of your fish and other aquatic organisms. For most aquarium fish, the ideal water hardness level is between 5-15 dGH. However, some fish species are more tolerant of high or low water hardness levels, so it is essential to research the specific needs of your fish before making any changes to your aquarium.
Q: How often should I perform water changes to decrease water hardness?
A: The frequency of water changes will depend on the specific needs of your aquarium and the level of water hardness. As a general rule, it is recommended to perform a 10-20% water change every week to 10 days to help maintain a healthy and thriving aquatic environment.
Q: Can I use tap water that is high in minerals for my aquarium?
A: No, it is not recommended to use tap water that is high in minerals for your aquarium. Tap water can contain high levels of dissolved minerals, which can be detrimental to the health of your fish and other aquatic organisms. Instead, it is recommended to use a water conditioner that removes minerals and other impurities from the water before adding it to your aquarium.

Q: How do I know if my aquarium is experiencing high water hardness?
A: There are several signs that your aquarium may be experiencing high water hardness, including:
- Scale buildup on the glass walls of the tank
- Fin damage or disease in your fish
- Difficulty in maintaining a stable water temperature
- Difficulty in maintaining a stable pH level
By monitoring the health and well-being of your fish and other aquatic organisms, you can determine if your aquarium is experiencing high water hardness and take steps to address the issue.
Q: Can I use a water conditioner that does not remove minerals to decrease water hardness?
A: No, it is not recommended to use a water conditioner that does not remove minerals to decrease water hardness. Water conditioners that do not remove minerals can actually increase the level of water hardness in your aquarium, which can be detrimental to the health of your fish and other aquatic organisms. Instead, it is recommended to use a water conditioner that removes minerals and other impurities from the water before adding it to your aquarium.
