A special sealant is simply an indispensable item for aquarium owners. This adhesive-based product helps prevent cracks and leaks in the aquarium seams.
What are the criteria for choosing an aquarium sealant?
Aquarium sealant is a product used to prevent leaks and cracks at the joints and corners of the aquarium. Adhesive sealant is completely safe and effective. Only you need to choose it according to certain criteria.
So the aquarium sealant should be flexible even after drying and retain its properties when exposed to sunlight. It is good if the aquarium sealant provides maximum adhesion to the surface. This will make the design more reliable. And of course, it should be easy to apply so that the process of processing the aquarium does not drag on for a long time. When choosing, be sure to pay attention to the composition of the adhesive sealant. It should not contain toxic components that can negatively affect the fish.
As for the cost, you will not be able to save money. It is better to purchase a more expensive material that meets all of the above requirements. Also, when buying, you need to carefully look at the expiration dates of the sealant, because this product loses its inherent properties over time.
Silicone, acrylic or polyurethane?
There are currently three groups of sealants on the market - acrylic, polyurethane and silicone. Acrylic products are generally not recommended for use in aquariums as they are not flexible enough. But they can be used for sealing external joints in terrariums.
Polyurethane aquarium sealant should only be used by inexperienced fish breeders. The composition of such products contains many harmful substances that can harm not only the fauna, but also the flora of the home reservoir.
Perhaps the best option would be a silicone-based sealant. It can be used for bonding and restoration as well as for sealing aquarium joints. Silicone sealant is characterized by increased elasticity and resistance to external influences. By the way, for aquarium purposes, it is recommended to use only a transparent sealant. Even a white sealant will not work, as it contains a dye that can negatively affect the health of aquarium fish. Silicone sealant can be applied not only in the event of a leak, but also for prevention.
