I. Physical Filtration and Water Quality Improvement
1. **Filtration Function of Pore Structure**
The surface and interior of the water - absorbing stone are filled with natural pores and fine cracks, similar to "biological filter media". It can adsorb suspended impurities in the water, such as uneaten bait and fish feces debris, assisting in physical filtration and reducing water turbidity.
2. **Carrier for Microbial Attachment**
The pores provide a habitat for beneficial bacteria like nitrifying bacteria, promoting the establishment of the nitrification system and accelerating the decomposition of toxic substances in the water, such as ammonia - nitrogen and nitrite, thus indirectly improving the water quality.

 II. Humidity Regulation and Micro - ecology
1. **Humidification through Water Evaporation**
The "water - absorbing" property of the water - absorbing stone keeps its surface moist. The evaporation of water can increase the air humidity around the fish tank (especially suitable for dry environments). However, care should be taken to avoid excessive humidity affecting electrical equipment.
2. **Simulating a Water - land Environment**
If part of the water - absorbing stone is exposed above the water surface, it can create a "semi - aquatic and semi - terrestrial" micro - ecology. This is suitable for raising turtles, amphibians, or moisture - loving plants (such as moss, sweet flag), expanding the ecological diversity of the fish tank.

 III. Landscape Beautification and Landscaping Functions
1. **Artistic Conception of Natural Landscape**
The water - absorbing stone has a loose texture and unique patterns. It can be carved or stacked into shapes like rockeries and canyons. When paired with aquatic plants and moss, it can create a natural landscape of mountains, forests, and streams, enhancing the ornamental value of the fish tank.
2. Flexible Landscaping Combinations**
 - **Aquatic Plant Fixing**: The pores can fix small aquatic plants (such as moss, Cryptocoryne parva), forming a three - dimensional landscape of "plants growing on the stone".
 - **Water Flow Guidance**: When combined with a water pump to create "waterfalls" or "fountain" effects, the water flowing through the stone increases the dissolved oxygen content and also enhances the dynamic beauty.
