If you purchased a prefabricated aquarium or decided to construct it yourself, then you cannot do without such accompanying material as a sealant. An effective agent successfully replaces glue and is not a liquid, but a viscous polymer-based composition. Hardening after application, the mass forms a seam that is elastic to varying degrees, depending on the type of product, which acquires good waterproofing qualities. Often, such paste-like helpers are indispensable in the treatment of cracks in the hull.
In addition to the ability to best tolerate stretching, the sealant is characterized by resistance to high pressure of water and air, temperature extremes, and exposure to sunlight. Its composition should be neutral to the materials of the entire structure, water, not cause allergic reactions and the death of local fauna and flora. According to all these requirements, silicone compositions are considered ideal for aquariums. What are the most popular of them, you will learn from our rating.
