How Kalkwasser Dramatically Increased Our Coral Growth

Kalkwasser was a game-changer for our tanks! In this post, we discuss how we were able to completely change the growth rate of our acropora. In just a few months some of our most stagnant acros quadrupled or more in size! We dive into what exactly is Kalk, how we use it, why we use it and why you should consider it in your tank. If you have ever been skeptical to try out kalk, our images in this blog are proof enough that kalk can be a game changer when used correctly.

What is Kalkwasser?

Kalkwasser, also known as calcium hydroxide, is a popular reef tank additive used to maintain optimal calcium and alkalinity levels. It is a fine white powder that is mixed with fresh RO/DI water to create a clear liquid solution. This solution is then dosed into the aquarium to supplement the calcium and alkalinity levels.

One of the benefits of using Kalkwasser is its ability to help raise pH levels in the aquarium. This is because the solution is highly alkaline and can neutralize acidic substances in the water. Additionally, Kalkwasser is relatively inexpensive compared to other reef tank additives, making it a cost-effective option for maintaining calcium and alkalinity levels.

However, it is important to note that Kalkwasser should be used carefully and in moderation. Overdosing can lead to a buildup of calcium and other minerals, which can be harmful to the inhabitants of the aquarium. It is also important to properly mix the solution and remove any leftover residue before dosing into the aquarium. We prefer to use Two Little Fishies Kalkwasser as we have found it is the least likely to gum up your system and mixes the best.

Benefits of Using Kalkwasser

Using Kalkwasser in your reef aquarium can provide several benefits. Here are some of the most important ones:

• Raises Calcium and Alkalinity: Kalkwasser is an excellent source of calcium and alkalinity, which are essential for the growth and health of corals, snails, and clams. By adding Kalkwasser to your tank, you can maintain the proper levels of calcium and alkalinity, which can help your reef thrive.
• Boosts pH: Kalkwasser is also known for its ability to boost pH levels in reef aquariums. This is particularly useful if you have a low pH problem in your tank. By adding Kalkwasser, you can help stabilize the pH and create a more stable environment for your reef inhabitants.
• Removes Carbon Dioxide: Kalkwasser has the ability to remove carbon dioxide from the water in your reef aquarium. Carbon dioxide can build up in your tank and cause pH to drop. By adding Kalkwasser, you can help remove carbon dioxide and prevent pH fluctuations.
• Easy to Use: Kalkwasser is relatively easy to use compared to other calcium and alkalinity supplements. It can be added directly to your tank or used in a dosing system. It is also relatively inexpensive compared to other supplements.

Overall, using Kalkwasser in your reef aquarium can provide several benefits that can help your reef thrive. It is important to note that Kalkwasser should be used in moderation and with caution, as adding too much can cause pH to rise too high and harm your reef inhabitants.

How to Use Kalkwasser

Preparing Kalkwasser Solution

Kalkwasser is a simple and straightforward method for maintaining calcium and alkalinity levels in a reef aquarium. To prepare the solution:

• Mix 1/2 to 1 teaspoon of Two Little Fishies kalkwasser powder per gallon of fresh water in a container.
• Stir the mixture vigorously until the powder is completely dissolved.
• Allow the mixture to settle for at least an hour before using it.

Dosing Kalkwasser Solution

Once the kalkwasser solution is prepared, it can be dosed into the aquarium. It is important to note that kalkwasser should be added slowly and carefully to avoid any sudden changes in pH or alkalinity levels. Here are some dosing tips:

• Start by adding a small amount of the solution to the aquarium. Make sure you are consistent each day.
• Gradually increase the amount of kalkwasser added over time, monitoring the pH and alkalinity levels closely.
• It is best to add kalkwasser to the aquarium at night when the pH levels are naturally lower.
• Use a dosing pump to ensure accurate and consistent dosing.
• Monitor the calcium and alkalinity levels regularly and adjust the dosing accordingly.

Remember, kalkwasser is just one method for maintaining calcium and alkalinity levels in a reef aquarium. It is important to research and understand other methods as well to determine the best approach for your specific aquarium needs.

FAQ Section

How do I start kalkwasser?

Kalkwasser is a great way to maintain calcium and alkalinity levels in your reef tank. To start using kalkwasser, you will need a few things:

• A container to mix the kalkwasser solution
• A way to add the kalkwasser solution to your tank, such as a dosing pump or gravity-fed drip system
• A way to measure the pH and alkalinity levels in your tank, such as test kits or a pH controller

Once you have these items, you can mix the kalkwasser solution according to the instructions on the package. It’s important to start slowly and monitor your pH and alkalinity levels closely. Gradually increase the amount of kalkwasser you add to your tank until you reach the desired levels.

How long does it take for kalkwasser to work?

Kalkwasser can take several hours to fully dissolve in your tank, so it’s important to add it slowly over time. You should start to see an increase in your calcium and alkalinity levels within a few days of starting to use kalkwasser. However, it’s important to continue monitoring your levels and adjusting your dosing as necessary.

What are the cons of kalkwasser?

While kalkwasser is a great way to maintain calcium and alkalinity levels in your reef tank, there are some potential downsides to using it:

• Kalkwasser can raise the pH of your tank, which can be harmful to some species of fish and invertebrates.
• Overdosing kalkwasser can lead to high levels of calcium and alkalinity, which can be harmful to your tank inhabitants.
• Kalkwasser can be messy to mix and use, and it can also leave a white residue on your equipment and tank walls.

Despite these potential downsides, many reef tank hobbyists find kalkwasser to be a reliable and effective way to maintain calcium and alkalinity levels in their tanks.
