Some aquarium substrates feature porous structures that can create an excellent environment for beneficial bacteria, aiding the growth of both plants and animals in the tank. Others, due to their high calcium content, may alter the water's pH, which can be harmful or even fatal to certain fish species. Additionally, some substrates act as filters and may release elements into the water that are not safe for fish. Therefore, it’s essential to understand the needs of the fish and plants in your aquarium when selecting a substrate and their specific requirements for water pH.
It's important to note that regardless of the species, avoid using sea sand and stones that contain any metal in aquariums, as they can pose a significant risk to fish, which are particularly sensitive to water quality and toxic substances. Be cautious of stores with dubious reputations that may sell unnatural or dyed substrates, which can present an even greater hazard.
Dolomite substrate is completely natural and highly sought after by customers. However, it is not suitable for all situations. With its high calcium content, dolomite dramatically alters the water's characteristics and properties. As such, it is best suited for specific aquariums with fish species that thrive in alkaline and hard water. It is not recommended for planted aquariums. However, it is ideal for species from lakes like Malawi, Tanganyika, and Victoria. In these environments, this substrate helps stabilize water parameters and enhances its essential qualities. Aquael's dolomite gravel also boasts remarkable purity, free from harmful pollutants that could endanger fish health. Many less reputable manufacturers neglect the purity of their products, resulting in substrates that may leach toxic compounds into the water.
It’s worth noting that most aquarium substrates are sterile, meaning they lack sufficient minerals. Many novice aquarists do not realize this and miss out on the full potential of their tanks. A beneficial practice is to combine the substrate with additional fertilizers, serving as a base for the dolomite substrate. This type of substrate is rich in nutrients, which promote healthy plant growth by enhancing rooting and providing optimal conditions for photosynthesis. Some even help mitigate algae growth.
Dolomite substrate is available in various colors, including black and gray, but the most popular options remain beige and white, as they offer a versatile choice. These colors beautifully enhance aesthetically arranged aquariums, providing an ideal backdrop for all aquatic creatures. The substrate consists of small granules, making it perfectly suited for all types of aquarium decorations.
