What Rocks Are Bad For Aquariums? Avoid These Pitfalls!

What types of rocks should you steer clear of when setting up an aquarium? It’s important to avoid rocks that are highly calcareous, as they contain an excessive amount of calcium. Additionally, always be cautious about using sharp-edged rocks in your aquarium, as they have the potential to harm your fish. When choosing rocks for your aquatic habitat, consider the potential for excessive calcium content and sharp edges to ensure the safety and well-being of your aquatic pets.

Which rocks are suitable for aquariums, especially in the context of saltwater tanks, is a commonly asked question among aquarium enthusiasts. There are two main types of rocks commonly used in saltwater aquariums: real live rock and synthetic live rock. Synthetic live rock is considered inert and will not dissolve in the aquarium environment, making it a stable choice for aquarists. On the other hand, real live rock is a bit more complex. It is composed of aragonite, a crystallized form of calcium carbonate, which is derived from the remnants of coral skeletons. This natural rock not only adds aesthetic appeal but also contributes to the aquarium’s water chemistry in a unique way. Real live rock is often sought after by saltwater hobbyists for its ability to introduce beneficial microorganisms and help maintain water quality. Understanding the differences between these rock types is essential for creating a thriving and balanced saltwater aquarium ecosystem. (Published on June 12, 2022)
