Mantis Aqua Glue (4g X 25pcs) – Ms-015 — Gel adhesive that cures underwater for frags and plants
A coral frag drifts off a plug the moment it is lowered back into the tank, and a glue that needs a dry surface is no help once the rock is wet. Mantis Aqua Glue (4g X 25pcs) – Ms-015 (SKU: MA069803) is a gel-type adhesive supplied as 25 individual 4 g tubes, made to bond coral fragments to plugs or rock and to fix live or artificial plants to ornaments and aquascape hardscape. It sets while fully submerged, so a frag can be held against a plug or a stem tucked against driftwood and glued in place without lifting the piece out of the water. The gel consistency stays where it is squeezed rather than running off a curved plug or an angled rock face, which matters when the join has to hold before the piece is released.
Each of the 25 tubes holds 4 g, enough for one or two frags or a small plant placement, so a fresh tube is opened for every job rather than working from a shared bottle that skins over between uses. The small single-dose format suits a frag swap, a club trade table or a weekend spent replanting a tank, where several separate bonds are needed in one sitting and a part-used tube would otherwise go to waste. It is suited to both freshwater and marine aquariums, so the same pack glues a coral frag rack one day and ties a java fern to a piece of wood the next. There is no mixing or activator step: the gel is applied directly from the tube and holds the piece with a short, steady press while it takes hold, a longer hold helping on a heavier or awkward-shaped frag.
Usage & Application
When to Use
- Coral fragging: Mounting a freshly cut frag onto a ceramic plug or frag rack before it goes onto the rock.
- Rescaping and replanting: Fixing live or artificial plants to driftwood, rock or ornaments that keep drifting loose.
- Underwater repairs: Re-securing a frag, plug or small ornament that has come away without draining the tank.
- Either water type: Freshwater planted tanks and marine reef systems both take the same tube.
How to Use
- Position first: Hold the frag, plug or plant against the spot it needs to sit, in or out of the water.
- Apply a small bead: Squeeze a small amount from the tube onto the contact point only.
- Hold until set: Keep the piece steady and in contact for a short, firm press while the gel grips.
- Open a fresh tube per job: Use one tube per frag or plant rather than returning to a part-used one later.
