The global market for aquatic water quality improvers continues to expand, and the iteration of eco-friendly filter material technology is accelerating

The global market for aquatic water quality treatment products maintains stable and high-speed growth, with a market size exceeding 2.08 billion US dollars in 2026 and expected to reach 5.07 billion US dollars by 2035, with a compound annual growth rate of 10.4%. The three major factors of popularization of home aquarium landscaping, expansion of commercial large-scale aquariums, and popularization of ecological tank feeding concepts continue to drive the demand for water quality improvers, biochemical filter materials, and aquatic landscaping crafts. From the perspective of the domestic market structure, environmentally friendly biochemical filter materials account for half of the aquatic supporting products. In 2024, the sales of domestic filter materials reached 3.21 billion yuan, among which the market share of nano porous ceramics and biologically activated carbon fiber composite high-end filter materials continues to rise. Consumers are no longer satisfied with basic filter materials, but pay more attention to the core performance of filter materials such as bacterial cultivation efficiency, service life, and no secondary pollution, which forces upstream manufacturing enterprises to continue to carry out material formula and sintering process research and development.
The water quality improvement agent track is showing a clear trend of technological upgrading, with traditional single chemical stabilizers gradually being replaced by composite biological enzymes and nitrifying bacterial preparations. The new generation of products can simultaneously remove chlorine, heavy metals, ammonia nitrogen, and nitrite from water bodies, while also adjusting pH values and maintaining beneficial bacterial communities in water bodies, adapting to the feeding needs of different aquatic organisms such as dragonfish, tropical fish, and turtles. The industry's R&D department continues to focus on green additive free formulas, abandoning irritating chemical raw materials and using food grade microbial strains to avoid chronic damage to ornamental organisms caused by long-term use. The number of patent applications for related new amendments has increased by an average of 27% in the past three years. At the same time, the aquarium landscaping background wall and craft decoration track have simultaneously exploded, and young consumer groups are enthusiastic about creating immersive ecological fish tanks, driving sales of simulated rock, sunken wood, and resin landscaping products to increase. Manufacturing enterprises have simultaneously optimized their production processes, using odorless and environmentally friendly resin raw materials that meet international food contact safety standards, achieving an integrated layout of multiple categories including feed, filter materials, and landscaping decorations. In terms of industrial chain clusters, the Yangtze River Delta and Pearl River Delta have formed a complete upstream and downstream supporting system. The supply of upstream mineral raw materials and polymer materials is stable, and midstream manufacturing enterprises rely on industrial clusters to reduce production costs. Downstream connections are made with tens of thousands of domestic aquarium stores and cross-border e-commerce channels. Overseas export orders are increasing year by year, and there is a strong demand for domestically produced cost-effective water quality supporting products in Southeast Asia, Europe and America, becoming a new growth curve for the industry.
