Shuode aquarium silicone is a specialized, non-toxic sealant designed for fish tanks, aquariums, and aquatic environments. Formulated to be 100% safe for fish, plants, and invertebrates, it creates a permanent, watertight seal that prevents leaks even under constant water pressure.

With strong adhesion to glass, acrylic, and ceramic, it’s ideal for tank assembly, seam repairs, attaching backgrounds, or securing equipment like filters and heaters. Resistant to mold, mildew, and water degradation, it maintains flexibility to withstand temperature changes and minor tank shifts.

Compliant with global safety standards, our aquarium sealant cures quickly (24–48 hours) and remains inert in water, ensuring no harmful chemicals leach into the aquatic ecosystem. Available in clear or black, in various sizes for home hobbyists and commercial aquarium builders.
