Some aquarium substrates, because of their porous nature, can serve as an excellent environment for beneficial bacteria that assist in the growth of both fauna and flora in the aquarium. Others, due to a high calcium content, can alter the pH level of the water, potentially harming certain fish species and posing a serious risk to their well-being. Additionally, some substrates function as filters, which may inadvertently release elements into the water that are not suitable for fish. Therefore, when selecting an aquarium substrate, it's important to understand the specific needs of the fish and plants in your tank, especially concerning their water pH preferences.
Always remember that regardless of the fish or plant species, sea sand and stones with even trace amounts of metal should be avoided in aquariums. Both can be extremely hazardous to fish, which are particularly sensitive to water quality and harmful substances. Be cautious of stores with dubious reputations that may carry unnatural or dyed substrates, as these can pose even greater risks.
Dolomite substrate is entirely natural and is highly sought after by consumers. However, it is not suitable for every aquarium setup. Because dolomite is rich in calcium, it significantly alters the water's characteristics and properties. Thus, it should only be used in aquariums with specific fish species that thrive in alkaline, hard water. It is not recommended for planted aquariums. On the other hand, it is ideal for fish from regions like Lake Malawi, Tanganyika, and Victoria, as it helps stabilize water parameters and enhances overall water quality. The dolomite gravel produced by Aquael is also known for its exceptional purity—free from harmful contaminants that could endanger the health of your fish. Many lesser-known manufacturers do not prioritize product purity, leading to substrates that can leach toxic compounds into the water with unpredictable effects.
It's essential to note that most aquarium substrates are sterile, meaning they lack adequate minerals. Many novice aquarists are unaware of this, which can limit the potential of their tank. A beneficial practice is to use a substrate layer, which serves as additional fertilizer beneath the dolomite substrate. This substrate is rich in nutrients that support plant growth by enhancing root development and providing optimal conditions for photosynthesis. Some of these substrates can even help minimize algae proliferation.
Dolomite substrate is available in various colors, including black and gray, but the most popular choices remain beige and white, as these colors provide a versatile backdrop for your aquarium's aesthetic. This color enhances the visual appeal of well-arranged aquariums, creating an ideal setting for all aquarium inhabitants. The substrate consists of small granules, ensuring compatibility with a wide range of aquarium decorations.
