Calcium is an essential element for the growth and health of corals in a reef tank. However, if the calcium levels in your tank become too high, it can lead to several issues and even harm the inhabitants of your tank. In order to maintain a balanced and healthy reef tank, it is important to monitor and control the calcium levels regularly.
Why is high calcium a problem?
High calcium levels can cause coral bleaching, which is the loss of the symbiotic algae that provide corals with their color and energy. This can lead to reduced coral growth, weakened immune systems, and increased vulnerability to diseases. Additionally, high calcium levels can also result in the precipitation of calcium carbonate, forming unsightly and potentially damaging deposits on corals, equipment, and tank walls.
How to lower calcium levels?
1. Water Changes:
Perform regular water changes to dilute the calcium levels in your tank. Use a high-quality salt mix that has a lower calcium content to help lower the overall calcium levels in your tank.
2. Adjust Calcium Reactor:
If you are using a calcium reactor, make sure to adjust the flow rate of the reactor and monitor the pH levels. Lowering the flow rate can decrease the amount of calcium being added to the tank, effectively lowering the calcium levels.
3. Use Chemical Additives:
Consider using chemical additives specifically designed to lower calcium levels in reef tanks. These additives work by binding with the excess calcium and precipitating it out of the water. Follow the instructions provided by the manufacturer for dosage and application.
Maintaining the correct calcium levels in your reef tank is crucial for the health and growth of your corals. By regularly monitoring and controlling the calcium levels, you can ensure a balanced and thriving reef tank environment for your aquatic inhabitants.
Understanding Calcium Levels in Reef Tanks
Calcium is an essential element for the growth and health of corals and other invertebrates in reef tanks. Maintaining the proper calcium levels is crucial to ensure the well-being of your tank inhabitants.
When calcium levels are too high, it can lead to problems such as excessive algae growth, coral bleaching, and decreased overall water quality. On the other hand, low calcium levels can hinder coral growth and prevent them from developing their calcified skeletons.
It is recommended to keep calcium levels in reef tanks between 380 and 450 ppm (parts per million). Regular testing of calcium levels should be conducted using a reliable test kit. If the levels are outside the recommended range, corrective measures should be taken.
Causes of High Calcium Levels
Causes of Low Calcium Levels

Regular monitoring of calcium levels and implementing these corrective measures will help you maintain optimal calcium levels in your reef tank and promote the health and growth of your corals and other invertebrates.
Consequences of High Calcium Levels
Having high levels of calcium in your reef tank can have several negative consequences for your coral and other marine life. It is important to monitor and control calcium levels to ensure a healthy and balanced environment. Here are some potential problems that can arise from high calcium levels:
1. Algae Overgrowth
Excessive calcium can promote the growth of unwanted algae in your reef tank. This can lead to the overgrowth of unsightly algae on rocks, corals, and other surfaces, affecting the overall aesthetic appeal of your tank. High calcium levels provide an ideal environment for algae to thrive, so keeping calcium levels in check is crucial to prevent algae issues.
2. Coral Health Issues
While calcium is important for coral growth, excessively high levels can actually harm corals. High calcium levels can cause calcium precipitation on coral tissues, leading to necrosis or tissue death. This can result in the death of coral colonies or a decline in their overall health. Maintaining the correct calcium levels is essential for the well-being of your coral inhabitants.
3. pH Imbalance
High calcium levels can disrupt the pH balance in your reef tank. Calcium reacts with carbonates and bicarbonates in the water, affecting the acid-base balance. This can result in a decrease in pH, making the tank more acidic. An imbalanced pH can have detrimental effects on the health of your marine life, causing stress and potentially leading to their demise.
It is important to regularly test and adjust calcium levels in your reef tank to avoid these negative consequences. Consulting with a marine aquarium specialist can help you maintain the appropriate calcium levels for the specific needs of your tank inhabitants.
Methods to Lower Calcium Levels
When calcium levels in a reef tank become too high, it is important to take action to lower them in order to maintain a healthy aquarium ecosystem. There are several methods that can be used to decrease calcium levels:
Water changes: Regular water changes can help dilute the calcium concentration in the tank. It is recommended to perform regular partial water changes using reverse osmosis (RO) water to lower calcium levels.
Using a calcium reactor: A calcium reactor is a device that helps to regulate calcium levels in a reef tank by introducing carbon dioxide to dissolve calcium carbonate media. This can help to lower excessively high calcium levels.
Reducing calcium supplementation: If calcium levels are consistently high, it may be necessary to decrease or even stop adding calcium supplements to the tank. Regular testing and monitoring of calcium levels can help determine if this is necessary.
Increasing water flow: Increasing water flow in the tank can help promote the growth of coralline algae, which can help to consume excess calcium in the water. This can be achieved by adding additional powerheads or adjusting the placement of existing circulation pumps.
Using a calcium carbonate reactor: A calcium carbonate reactor can help to remove excess calcium from the water by using a chemical filter media that binds to and removes the excess calcium. This method can be effective in lowering calcium levels in the tank.
It is important to note that while these methods can help to lower calcium levels, it is crucial to address the underlying cause of high calcium levels in order to prevent them from recurring in the future. Regular water testing and monitoring, as well as proper maintenance and care of the reef tank, can help maintain stable and balanced calcium levels over time.
Monitoring and Maintaining Optimal Calcium Levels
In a reef tank, maintaining proper calcium levels is crucial for the health and growth of corals, as well as other calcium-dependent organisms. Regular monitoring and maintenance of calcium levels are essential to ensure a stable and balanced reef environment. Here are some steps you can take to monitor and maintain optimal calcium levels in your reef tank:
1. Testing Calcium Levels
Regularly test the calcium levels in your reef tank using a reliable calcium test kit. This will give you an idea of the current calcium concentration in the water and help you determine if any adjustments are necessary.
