AquaMaxx Reef Welder: Build a Bonsai Tree, Glue Frags to Rock, or Repair a Cracked Skimmer

As reef hobbyists, I am sure we’ve all experienced using different types of glues in our aquariums. I’m sure we have all at some point glued our fingers together with super glue gel, or have had our skimmers go nuts after using epoxy.

We would like to introduce to you a new type of aquarium safe material that has some amazing uses in and around your tank; the AquaMaxx Reef Welder. What makes the Reef Welder different is that it is not actually a glue: it is a thermo-activated, moldable plastic.

Reef Welder is also available in purple so it blends in better with coralline algae.


The Reef Welder comes in the form of small beads. Simply heat up some water and drop the beads into the water for about two minutes. The water does not have to be boiling hot just warm enough to melt the beads. Once heated, these beads turn transparent and become soft and moldable. Simply remove the beads and knead them together to form a ball of moldable plastic. The material will harden in a few minutes as it cools.

The really cool part is the Reef Welder is perfectly suitable to be re-heated over and over again so if you mess up the first time, you can always give it another shot. Another big advantage of the Reef Welder is that it is completely inert, so will not make your skimmer over-foam like epoxy.

There are two types of Reef Welder available: the regular white version and a purple version. We really like the purple version as it turns a pinkish-purple color and blends very nicely with coralline algae inside your tank.

When Reef Welder’s plastic pellets are melted, they fuse together and become soft.


The material is flexible yet extremely strong, so it can be used for a large variety of applications. Similar to using two-part epoxy sticks, the Reef Welder is great for gluing rock pieces together to create unique aquascapes or attaching hard corals to live rock.

In our office aquarium, we were running out of room and needed to create a little more spacious aquascape inside the tank. We also had a pretty bad problem with some palys that were out competing other corals for space so they needed to get removed.

We took a few pieces of rock and used the Reef Welder to create a new rock structure for the tank. Next, we fragged off all of the corals from the old rock, removed it, and cleaned out the prolific palys.  We placed the new rock structure inside the tank and re-attached all of our corals.  The tank looks much better now and all of the corals have more room to grow!

We put Reef Welder to the test by building a new rock structure in our Innovative Marine SR-80 aquarium.


Take a look at this awesome bonsai tree structure that we created using Reef Welder an AquaMaxx Dry Live Rock for our Project Manager, Joseph!

Joseph put this cool bonsai tree made from AquaMaxx rock and Reef Welder in his 34-gallon Solana aquarium.


We have used the Reef Welder to repair frayed powerhead cords, made custom brackets for an ATO sensor, used it to level an aquarium stand, made risers for live rock and even used it as a quick fix to repair a cracked skimmer chamber. I am sure you guys can think of even more great uses and please feel free to share your ideas with us.

If you are tired of stinky epoxy sticks that make your skimmer go crazy and done gluing your fingertips together with gel glue that sticks to everything, definitely give the Reef Welder a try. Being so versatile and handy, the Reef Welder is a great to have around the aquarium.
