AquaVitro Bond - 100l
A coral mount you can melt, reshape and reuse. AquaVitro Bond is a low-melting-temperature thermoplastic adhesive from Seachem's aquavitro line, used to fix coral frags to rock or to fuse aquascaping rockwork together. Unlike a cyanoacrylate glue or two-part epoxy, Bond softens again in hot water, so a placement that isn't quite right can be reheated and reshaped rather than chiselled off and redone from scratch.
Key features
- Reheatable and reworkable - soften it in hot water as many times as you need to get a placement right, instead of committing on the first attempt.
- Non-toxic and inert once set - Seachem states it has no impact on aquarium water chemistry, so it can be used directly in a stocked reef tank.
- No mixing, no cure time to plan around - unlike two-part epoxy putty, there's nothing to measure or combine; heat, knead, place.
- Works underwater or out of the tank - shape it before placing a frag, or mould it directly against wet rock.

Seachem does not publish a full chemical composition for Bond beyond describing it as a low-melting-temperature plastic; a full safety data sheet is available from Seachem on request for anyone who needs the complete breakdown.
How to use it
- Add the amount of Bond you need to hot water at approximately 45°C (113°F) - do not boil it.
- Wait for it to change from opaque white to clear, which signals it has fully softened.
- Remove it from the water and knead it to work out any trapped air or water pockets.
- Shape it around the frag plug or rock join while it's still workable - you have roughly 10-15 minutes before it firms up.
- Hold or prop the piece in place while it cools and hardens fully.
It can be reheated and reworked as many times as needed if a placement doesn't hold or needs adjusting.
Suitable for, and not suitable for
Suitable for: mounting coral frags to plugs or display rock, and fusing loose aquascaping rock into a stable structure, in both freshwater and marine or reef tanks.
Not suitable for: permanent structural bonding under heavy mechanical load - it is a mounting putty, not a construction adhesive, and a large rockwork structure should still be built to stand on its own rather than rely on Bond to hold its weight.
Care and safety
Heat only to the point where the putty turns clear - overheating it makes it difficult to handle safely and doesn't improve how it sets. Let it cool before final placement checks, since it stays workable and can be reshaped by hand while warm.
Goes well with
- Aquavitro Coral Cutter 18cm - to take the frag you're about to mount.
- Aquavitro Crescent Coral Cutter 19cm - the curved-jaw alternative for awkward angles.
Warranty and delivery
As a consumable putty, Bond is not covered by a manufacturer warranty term in the usual sense; your rights under the Australian Consumer Law apply to any product that is faulty or not as described. It is not a dangerous good and ships as standard parcel freight.
Common questions
Is AquaVitro Bond safe for fish, coral and invertebrates?
Seachem states it is non-toxic and inert once set, with no impact on aquarium chemistry, and it is sold specifically for use in stocked reef and planted systems.
Can I reuse it if I make a mistake?
Yes. Reheat it in hot water until it turns clear again and it can be reshaped and reused, which is the main advantage over a one-shot glue or epoxy.
Does it work underwater?
Once softened in hot water, it stays workable long enough to press against wet rock or a frag plug and hold its shape as it cools, so it does not need to be applied to a fully dry surface.
How is this different from coral frag glue or epoxy putty?
Cyanoacrylate glue sets in seconds with no working time, and two-part epoxy has to be mixed and cures permanently. Bond is reheatable and reworkable indefinitely, at the cost of a slightly longer setup step to soften it first.
