Onyx Sand™ is a premium, naturally dark gray sand that can beautifully enhance the look of any aquarium. It's ideal for freshwater planted aquariums as it helps maintain optimal KH levels. You can use it in any aquarium setting. While it works best as a standalone substrate, you can also mix it with other gravels, and there's no need for gravel modifiers like laterite. This sand isn't chemically coated or treated. As a carbonate - rich sand, it has a gentle buffering ability that can raise the pH by 0.1 - 0.5 units, depending on your source water. Once added to your aquarium, it lasts for the whole life of the tank and doesn't need to be replaced. Available in 3.5 kg size. Key features include being a top - notch natural sand for planted aquariums, long - lasting for the aquarium's life, supporting ideal KH levels, and being rich in carbonates.
Using Onyx Sand™ in your aquarium is easy. First, rinse the sand thoroughly under running water to remove any dust or debris. Then, simply add it to your aquarium as a substrate. You can use it alone or mix it with other gravels. If you're setting up a planted aquarium, this sand will help support the optimal KH levels for your plants. Remember, since it's a carbonate - rich sand, it may slightly raise the pH of your water, so check your water parameters regularly. You don't need to add gravel modifiers like laterite.
