What Kind Of Super Glue Can You Use In An Aquarium?

There are a variety of glues that help fix broken equipment or decorate aquariums.

Most of them are safe adhesives and are commonly used in aquariums.

Below are some types of adhesives that can be used in aquariums:

  • Cyanoacrylate super glue: Cyanoacrylate glue is made of acrylic resin. Its acrylic molecule transforms into a plastic state once applied to a surface. It works best on a surface with some moisture to form a strong bond between the two connecting objects. It’s the most commonly used glue in aquariums.
  • Silicone sealant: Silicone is a multipurpose adhesive, and sealants create a protective waterproof seal on the applied surface. Gorilla glue is a silicone sealant that’s also used in aquariums. It is waterproof and resistant to temperature variations.
  • Hot glue: Hot glue can be used in an aquarium. However, try using it to fix objects and decorations that are not submerged in water. Hot glue is water-resistant but doesn’t create a waterproof bond between two objects.
  • Epoxy: Epoxy glue can be used to fix pipe leaks and other equipment issues. You can also use it to attach rocks and decorations. However, epoxy is not safe for aquarium use. You can only use it to fix aquarium equipment that is not submerged in water.

All the above glues can be used for aquariums. However, super glue is the best and safe option for aquariums.

So, let’s now understand if you can use super glue on aquarium plants.

Can You Super Glue Aquarium Plants?

Yes, you can super glue aquarium plants. Cyanoacrylate, or super glue, is a liquid acrylic that creates an acrylic bond between the plants and the surface.

Decorating an aquarium with plants, rocks, etc., to create an underwater garden is known as aquascaping.

It has numerous benefits for an aquarium.

Aquascaping provides shelter to the inhabitant, filters water, and enhances the beauty of an aquarium.

You can use live plants like Amazon Sword, Anubias Nana, Dwarf Baby Tears, Dwarf Hairgrass, Dwarf Sagittaria, Java Fern, and Java Moss to create a stunning aquascape inside an aquarium.

Aquascaping can be done using inert substrates like gravel and sand.

However, use aquarium-safe, nutrient-rich soil substrates for best results.

They provide better results as they contain helpful nutrients for plants.

Let’s now understand how you can super glue aquarium plants.

How To Super Glue Aquarium Plants?

Cyanoacrylate or super glue is the best adhesive to fix aquatic plants in an aquarium.

Super glue is thick and doesn’t run down on the surface.

Instead, it creates an acrylic bond between the plant and the surface on which the plant is placed.

Given below are the steps to super glue aquarium plants:

  1. To open the super glue gel, pierce the top with the screw-on cap.
  2. Remove the plant from the pot and gently run the water over its roots to remove the cotton-like material.
  3. Clean the roots with your hands. Now, find the rhizome; it’s an underground plant stem that can produce a new plant’s shoot and root system.
  4. Locate the best part of the surface you want to place the plant on. It can be a rock, sand, gravel, or any substrate on which you want to fix the plant.
  5. Use a paper tissue or towel to dry the plant roots properly before applying the super glue gel.
  6. Apply a layer of super glue gel on the rock, stone, driftwood, or any other surface on which you will place the live plants.
  7. Next, you have to press both the roots and the rhizome vertically above the surface and hold them together for few minutes till the roots of the plant firmly hold onto the surface.
  8. Continue this process with other live plants that you want to add. Make sure to complete the process in 10 to 15 minutes to avoid the plants from drying outside the water.
  9. Place them inside the water to create a stunning display in the aquarium.

Finally, allow the plants to grow and enjoy the beautiful display you have created inside your aquarium.

Can You Use Super Glue In A Saltwater Tank?

Yes, you can use super glue in a saltwater tank. It can quickly fix broken pieces of equipment and also attach decorations to the aquarium.

In addition, you can use it to add live plants that are necessary for saltwater aquariums.

Aquatic plants help manage the ecosystem within the aquarium and also provide shelter for the fish.

In a saltwater tank, you can use super glue on rocks, stones, shells, live plants, driftwood, and corals.

Apply super glue gel on the surface of the rocks, stones, or driftwood and press the roots and the rhizome of the plants vertically till they bond with each other.

Super glue makes aquascaping possible in a saltwater aquarium.

Aquascaping improves the ecosystem by keeping the aquarium water clean and enhancing the saltwater aquarium’s overall display.

Can You Use Super Glue In A Reef Tank?

A reef tank is a marine aquarium where coral reefs, marine invertebrates, and fish are kept together.

A reef tank houses different species of fish, crabs, shrimps, starfish, corals, etc.

Super glue can help set up marine aquarium equipment, decorations, and aquascaping items.

In addition, it will help create a stunning display of the coral reef environment.

Besides intense lighting and stable water parameters, a reef tank also needs turbulent water movement.

Super glue becomes inert when it comes in contact with water and can quickly fix and hold the objects glued to the surface inside the tank.

Corals thrive best in reef aquariums. You can use live rocks to place corals inside the reef tank.

Some soft corals like acans, favia, and micromussa will attach to the rocks on their own.

On the other hand, super glue can mount coral frags on rocks, plugs, and other surfaces.

It will help fix the coral on the desired surfaces and enhance the look of the reef tank.
