I. Physical Filtration and Water Quality Improvement
1. **Impurity Adsorption by Pore Structure**
There are a large number of irregular pores on the surface and inside of pumice, similar to a "natural sponge". It can adsorb impurities in the fish tank such as uneaten bait, feces, and suspended matter, assisting the physical filtration system in purifying the water quality and reducing water turbidity.
2. **Slow - release of Minerals**
Pumice contains minerals such as calcium, magnesium, and potassium. These can be slowly released in water, adjusting the water hardness (GH) and pH value, providing more suitable living conditions for fish that prefer a weakly alkaline or hard - water environment, such as cichlids from the three African Great Lakes.

 II. Biological Filtration and Ecological Balance
1. **Cultivation of Beneficial Bacteria**
The porous structure provides a large attachment surface area for beneficial microorganisms such as nitrifying bacteria and denitrifying bacteria, serving as an important carrier for biological filtration. These bacteria can decompose toxic substances in the water such as ammonia - nitrogen and nitrite, maintaining stable water quality.
2. **Promotion of Micro - ecological Cycle**
Algae and microorganisms can grow in the gaps of pumice, providing habitats and food sources for small fish, shrimps, and snails, improving the food chain in the fish tank and enhancing the biodiversity of the ecosystem.

III. Landscape Creation and Fish Habitat
1. **Simulating the Natural Environment**
Pumice is lightweight and has a unique shape (mostly porous and uneven). It can be stacked or placed individually. When paired with landscaping materials such as aquatic plants and driftwood, it can create natural landscapes such as streams and reefs, enhancing the ornamental value of the fish tank.
2. **Providing Shelter Space**
The holes and gaps provide places for small fish, shrimps, and snails to avoid natural enemies. It is especially suitable for fish species that like to hide, such as guppies and neon tetras, reducing their stress response.
3. **Beak - Grinding / Claw - Grinding Function**
Some fish (such as angelfish, dwarf cichlids) or ornamental snails will bite the surface of pumice to rub their beaks or shells, maintaining their physical health.

 IV. Special Uses: Adjusting Buoyancy and Water Quality
1. **Auxiliary Buoyancy Function**
Pumice has a low density and can float on the water surface (or partially exposed above the water surface). It can be used as a floating island carrier for planting aquatic plants such as water hyacinths and duckweeds, further optimizing the fish - tank landscape and enhancing its ecological functions.
