Preparation of Lava rocks 

Lava rocks are a popular choice for aquarium enthusiasts due to their natural appearance, porous texture, and ability to provide a healthy ecosystem for aquatic life. However, it is important to properly prepare lava rocks for aquarium use to ensure that they are safe for your pets.

The preparation process for lava rocks involves cleaning and sterilizing them to remove any impurities or harmful substances that may be present. Here are the steps to properly prepare lava rocks for aquarium use: 

Cleaning Lava rocks – How to clean Lava rocks before adding them to your Aquarium 

The first step that you have to follow is to clean the lava rocks. You will need a bucket, water and a brush for this. 

• Rinse the rocks: You will have to put the lava rocks in a bucket and then keep adding water to it until the water starts to become clear. This will remove any dust or debris that may be present on the surface. This will also help to loosen any dirt that may be stuck to the rocks.
• Scrub the rocks: The next step is to scrub the rocks. Use a stiff brush to scrub the rocks thoroughly. This will remove any remaining dirt or debris that may be stuck to the surface of the rocks.
• Soak the rocks: Soak the rocks in a bucket of water for a few hours. This will help to loosen any remaining debris and make it easier to clean them.

Sterilising Lava rocks 

After cleaning them and getting rid of any kind of dirt, you must sterilize the rocks. This is important as this will eradicate all kinds of bacteria and harmful substances that the rock contains. 

• Boil the Lava Rocks : After cleaning them, you can boil them to sterilize the rocks. Get a pot big enough to fit the lava rocks that you have and fill it completely with water. Add the lava rocks to it and boil them for about 30 minutes. Do not boil any longer than that for the rocks might lose their rigidity and texture. 
• Boiling will ensure that toxic substances and bacteria are removed from it. After boiling wipe them off and keep them ready for the next step. 

• Soak in a bleach solution : The next step requires you to soak them in a bleach solution, so get your old clothes on and prepare the bleach solution. 
• Create a solution of bleach and water in a ratio of 1:9 (1 part bleach and 9 parts water). Soak the rocks in this solution for at least 24 hours. This will help to sterilize the rocks and kill any harmful bacteria or parasites that may be present. 
• Then remove the rocks and them rinse the lava rocks thoroughly. Then allow the rocks to air dry completely before adding them to the aquarium. This will prevent any chemicals or residues from contaminating the aquarium water. 

Testing pH level of Lava rocks 

Before adding lava rocks to your aquarium, it is important to test their pH level to ensure that they are compatible with the pH level of the aquarium water.

Testing the pH level of lava rocks is a simple process. Here are the steps to follow:

• Gather the necessary equipment: You will need a pH testing kit, a clean container, and a sample of the lava rocks.
• Prepare the test solution: Follow the instructions on the pH testing kit to prepare the test solution. This typically involves adding a few drops of the testing solution to the water sample.
• Add the lava rocks to the container: Place a sample of the lava rocks in the container with the test solution. The rocks should be fully submerged in the solution.
• Observe the color change: After a few minutes, observe the color change in the test solution. The pH level of the lava rocks can be determined by comparing the color of the solution to the color chart provided with the pH testing kit.

If the pH level of the lava rocks is significantly different from the pH level of the aquarium water, it may be necessary to adjust the pH level of the aquarium water or choose a different type of rock for the aquarium.
