We make two different types of cyanoacrylate-based super glue, the BRS General Bonding Glue which is a thinner consistency, and the BRS Extra Thick Super Glue Gel. The BRS Extra Thick is designed specifically for gluing frags because it retains its shape with a putty-like consistency that works great for holding frags in place. The BRS General Bonding glue works best when aquascaping or gluing rocks together along with general repairs around your tank.

BRS Extra Thick Super Glue Gel - Thick consistency gel style super glue that is best used for gluing frags to frags plugs or onto your rocks.
BRS General Bonding Super Glue - Water-like consistency that works great for gluing rocks together as well as general repairs such as bonding acrylic.

The biggest benefit of BRS Super Glue over leading brand names is the price, our glue is affordable and comes in bulk sizes should you find the need for a lot of glue. Behind Bob Smith Industries IC-Gel, we found our BRS Extra Thick Super Glue Gel to be the thickest glue available meaning it's suitable for gluing frags to frag plugs. In terms of strength, our glue will form equally strong bonds just like any of the leading brand name cyanoacrylate super glue products. 

Aquascaping using BRS General Bonding Super Glue

How To Glue Dry Live Rock Together

BRS General Bonding Glue is best for aquascaping and attaching rock pieces because the thin water-like consistency will easily coat the irregular rock surfaces. You won't end up with a big bulky mess of glue either because it doesn't create a mass of glue-like you get with gel-style glue.

  1. Test fit both pieces of rock to find the best area to glue them. Take advantage of the natural curves and crevices of the rock to help create a secure bond.  Remember, the glue only works on surfaces that touch each other.
  2. Using BRS General Bonding Glue, cover both rock surfaces that will be touching with an appropriate amount of glue.
  3. Spray the glue-covered areas with Insta-Set Super Glue Accelerator to speed up the curing.
  4. Immediately join and hold the two rocks together allowing a strong bond to form.  Usually will cure within 30-60 seconds using the Accelerator. 

If your gluing larger rocks or creating intricate aquascapes such as an NSA - Negative Space Aquascape, use Marco Rock E-Marco Aquascaping Mortar to cover the glued joints which will create a much stronger bond that will support those larger rocks or intricate structures. After the mortar has cured, you can use some BRS General Bonding Glue to attach sand and rock rubble over the cured mortar helping to camouflage everything together and maintain a natural-looking rock structure.

How To Glue Frags To Frag Plugs and Mounts

When gluing fresh frags to plugs or mounts, you want to work fast to minimize stress upon the coral. Always glue your frag out of the water which allows the glue to bond quickly.  Submerse the freshly glued coral frag only after you have allowed the glue to form a secure bond.  Do not expose a freshly glued frag to high water flow. 

  1. Be sure your frag plug is dry and do your best to dry the cut end of your coral frag with a clean towel. This ensures the glue stays tacky and sticks to the surfaces.  
  2. Place a dime-size dollop of BRS Extra Thick Super Glue Gel to the top of your frag plug.
  3. Push and hold the coral frag into the center of the glue. Firmly hold the frag in place for 60-90 seconds or until the glue cures enough to support the frag.
  4. Place the fresh frag into a frag rack and back into your aquarium. Allow it to cure for a few hours before exposing it to high flow. 

Sometimes a coral frag just doesn't want to stick to your plug. Often because of irregular or uneven coral cuts or larger frags (mini colonies) that are just too heavy.  In this case, using the "glue and epoxy sandwich" method is best. Form a small ball of two-part epoxy.  Add some glue to the frag, push it into the epoxy ball. Add glue to the top of the plug and push the epoxy with coral onto the top of the plug.  This creates a sandwich with epoxy in the middle and super glue on both sides.  The epoxy molds and supports the coral a little better while the super glue can form a strong bond to the epoxy itself.

How To Glue Frags To Submerged Live Rock

Attaching coral frags and coral pieces to your submerged live rock is possible and is always recommended to reduce the risk of corals falling off the rocks. The BRS Extra Thick works best here and can work all by itself if the frag is small and holds securely. If the frag is larger or won't hold, using some two-part epoxy like Tunze Coral Gum along with super glue is ideal. 

  1. Form a quarter-sized ball of two-part epoxy.
  2. Add a small amount of BRS Extra Thick Super Glue Gel to the cut end of your coral frag.
  3. Push the frag into the epoxy ball out of the water and then submerge it into the tank and push or mold the epoxy onto your rock.
  4. Form the epoxy into the crevices as best you can while holding the frag in place allowing it to set up. Usually 1-2 minutes.   
  5. Allow the coral frag to cure thoroughly for a couple of hours before exposing it to high water flow.
