From “wait and hope” to “set in seconds.”One quick spray on a CA glue joint kicks off aninstant cure— no more holding a frag in place for 60 seconds praying it doesn’t move. Works with any standardcyanoacrylate gel or liquidcoral / rock glue.
What It’s For
If you’ve everglued a coral frag to a plugand watched it shift, slide, or fall off because the CA glue took too long to set — INSTA-SET solves that. Spray it onto the freshly-glued joint and the cyanoacrylate kicks off into a hard bond in seconds. Same trick works foraquascape rock bonding,frag plug-to-mount attachments, and any DIY work where you’re using superglue and don’t want to babysit it. Reef-safe in normal usage volumes.

How to Use
Apply CA glue to your coral frag or rock as usual. Quickly spray a light mist of INSTA-SET onto the glue joint from a few inches away. The bond will cure to hardness in seconds rather than the usual 30–60+ second open time. Place and hold the frag for a few seconds, then release.Use sparingly— a light spray is all you need; over-application doesn’t speed things up further and wastes product. Avoid spraying directly into the water column.

FAQ
Will it kill my corals?
Used as directed — a quick spray on the glue joint, not into the water — INSTA-SET is reef-safe. Don’t dump the bottle into the tank, and don’t drench corals directly with the accelerator. The accelerator’s job is to speed the CA reaction, not to coat anything.
Do I have to use this brand’s glue with it?
No. INSTA-SET works with most standard cyanoacrylate (CA) glues — including hobby gels, liquids, and reef-branded frag glues. If your glue is a CA-based formula, the accelerator will work on it.
How long does the bottle last?
You only need a light spray per joint, so a 2 oz bottle handles a lot of fragging sessions. For a shop or heavy hobbyist, expect months of use; for casual fragging, well over a year.
Can I use it for non-reef projects?
Yes — it’s a general CA accelerator. Hobbyists also use it for model building, R/C, and other dry CA glue projects.
