The Best Aquarium-Safe Silicone Brands

Aqueon Silicone Aquarium Sealant

The Aqueon Silicone Aquarium Sealant has many advantages, among other things it is quite affordable and comes in a size for small jobs to reduce waste. It is easy to use and has a 48-hour curing time. Thanks to the well-designed closure, its useful period is significantly prolonged. In addition, it comes in two colors, clear and black to match the use.

One of the negative aspects of using the product of this aquarium safe silicone brand is that it works well with glass, but can’t be used on acrylic.

ASI Clear Aquarium Silicone Sealant

If you have in mind a larger project such as making a custom aquarium tank, the ASI Clear Aquarium Silicone Sealant is the best option. One tube (10 ounces) of this preparation has enough sealant to take care of a large tank or several smaller ones.

It is formulated for use in both freshwater and saltwater aquariums. Since it forms strong cohesive bonds to glass, the good thing is that you don’t need any primers to use this sealant. It is designed so that it can reach hard-to-reach places, ie the corners of the aquarium tank. This aquarium-safe silicone comes in both clear and black, too.

DAP is one of those aquarium-safe silicone brands that has a multitude of fans in this hobby. This long-lasting and 100% silicone rubber in contact with the aquarium glass creates a strong, waterproof seal, which will not shrink or crack due to its flexibility.

This All-Purpose Adhesive Sealant is labeled for this use so that we can distinguish it from other products in the company’s line. It is intended for both glass and acrylic aquariums.  Unfortunately, some of its disadvantages are that it is one-time-use-only silicone and has a rather unpleasant odor.

Loctite Clear Silicone Waterproof Sealant

Loctite really knows what they are doing! Their Clear Silicone Waterproof Sealant is multipurpose and can be used for sealing or repairing sinks, tubs, plumbing fixtures, windows, weather stripping, etc. However, it is important to emphasize that it is completely safe for aquarium use.

Among the main disadvantages of this aquarium-safe silicone is that you can’t use it for tanks larger than 30 gallons because of the lack of tensile strength. Also, due to the packaging, any subsequent use is questionable.

Apel’s aquarium sealant is completely (100%) silicone and is non-toxic. In addition, it doesn’t contain any additives or fungicides that can be harmful to aquatic life or beneficial bacteria found in the aquarium.

In terms of packaging and use, the product is supplied in a calk tube and requires a calk gun to use. It is most commonly used to seal seams, stop leaks, and even to affix decorations to the sides and bottom of an aquarium tank.

This product is made from 100% silicone without any additives, it can be used to seal tanks containing fish, corals, plants, and invertebrates.
