I. Physical Effects: Stabilizing Water Quality and Landscaping
1. **Regulating Water Quality pH**
Some Inkstones (such as rocks containing calcium carbonate) may slowly release minerals, slightly increasing the hardness and pH value of the water. This is suitable for ornamental fish that prefer weakly alkaline water, like cichlids from the three African Great Lakes. However, it should be noted that if the original water quality in the fish tank is acidic or if you are raising fish that prefer soft water (such as characins, dwarf cichlids), use it with caution to avoid water quality fluctuations.
2. Providing a Surface for Biological Attachment**
The rough surface of the Inkstone can serve as an attachment carrier for beneficial microorganisms such as nitrifying bacteria. It helps build the nitrification system in the fish tank, accelerating the decomposition of organic matter like fish feces and uneaten bait, thus indirectly purifying the water quality.
3. **Creating a Natural Landscape**
Inkstones have a deep and primitive color and unique textures. They can be paired with aquatic plants and driftwood to create natural - style tanks, South - American - style landscapes, or Japanese dry - landscape gardens, adding a sense of hierarchy and ornamental value to the fish tank. Their thick texture forms a sharp contrast with green plants, enhancing the visual effect.

 II. Ecological Effects: Simulating the Natural Environment
1. **Providing Shelter for Fish**
The gaps and caves formed after stacking Inkstones can serve as hiding spaces for small fish, shrimps, and snails. This is especially suitable for relatively timid fish (such as Corydoras catfish, killifish) or fish during the breeding period, reducing stress and attacks from their peers.
2. Facilitating Algae Control**
If the surface of the Inkstone is smooth and there is sufficient light, a small amount of algae (such as brown algae, green algae) may grow on it. This can become a food source for utility organisms such as snails and suckermouth catfish, helping to maintain the ecological balance in the fish tank. However, it is necessary to control the light intensity to avoid an algae bloom.
