Aqua Medic’s hot construct coral glue is a solvent free coral glue that is activated by soaking in hot water, kneaded and then used to affix coral frags or rocks for aquascaping.
Similar to other products we’ve seen on the market, like the AquaMaxx Reef Welder, it is a polymer that softens when heated in water around 65°C (150°F). They come in beads to allow for faster softening time and control of how much you use.
On paper, this seems like a better way to stick things together than your typically 2-part putty bonding agents or super glue. It should also be a little less impactful on your protein skimmer as these two are notorious for kicking skimmate into overdrive at times. Plus, it allows you to reuse it if needed by just warming it up again in hot water.
These polymer beads have been available for a while in other markets and hobbies and now seem to be making their way into the reef hobby just like we saw with other commodities like bio-pellets, GFO and others.
Aqua Medic’s Hot Construct coral glue retails around $8 for a 100 g pouch. No word on whether this is available in the U.S. market or if its just currently available in Europe.
