What material is good for fish tank?

There are many kinds of glass fish tanks, including ordinary glass fish tanks, float glass fish tanks, toughened glass fish tanks, acrylic glass fish tanks and plexiglass fish tanks. 1, ordinary glass: emerald green, fragile, low transparency, easy to age and deform when exposed to rain, try not to use it as a fish tank. 2. Float glass: Transparent float glass enters the tin bath through the control gate, floats on the surface of tin liquid due to gravity and its own surface tension, and then enters the slow cooling bath to make both sides of the glass smooth and uniform, and the ripples disappear. Dark green, smooth surface without ripple, good perspective and certain toughness. 3. Tempered glass: Tempered glass is a kind of high-strength safety glass, which is obtained by heating the glass to its softening point and then rapidly air-cooling. Under the same thickness, the bending strength of tempered glass is 4-5 times higher than that of ordinary glass, and the impact strength is 5 times higher than that of ordinary glass. The biggest feature of tempered glass is safety. This kind of broken glass is similar to honeycomb particles, which can avoid harm to human body. 4. Acrylic glass: a glass material similar to plexiglass and ordinary glass. It was originally used in airplanes. Most of the early corner fish tanks were made of acrylic glass, which was light in weight and strong in toughness. Must be integrated, easy to scratch, low transparency! 5. Plexiglass: It is an important thermoplastic with good transparency, chemical stability and easy dyeing and processing. But the strength is low, except for some small craft tanks (boxes), aquariums are generally not used.
