Loved it!
Works wonders! Had a gap in my tank and used this. After waiting for it to dry, didn’t take long at all, I filled my tank back up and there was no leakage! The glue isn’t too wet or runny which is quite nice. Doesn’t take long to cure either, it’s quite fast compared to other products I’ve seen. Great price!

Really strong, good
Its like superglue for aquarium. Works well it takes a while to dry completely if little bit more used. I found it fastest drying in a water. After i use it, wait 2,3 min then i stick it in the cold water that hardens the glue instantly. Good but not multiple time use, chaha like none superglue are multi use. After first time i couldn't use pointed end, after second cap wouldn't go on at all but its easy if you stick piece of foil on the end after each use. Its easy to remove it and it keeps it covered in worst case you could puncture the foil and use it again, so no problem:)

Best glue I've used on my reef
Good size tube will last for a long time. Frags stick quickly to plugs or rocks fast.

Dries white, adhesions of plant to rock didn’t last and the lid glued shut after a month
There is not a lot of information about application on the packaging, I used this to attach live plants to surfaces in my aquarium and The plants initially stuck but came off after a month, I wonder if it may be more suited as a hard surface / non living adhesive And not for plants. This dries white so is best to use in places out of sight. After 1 month of being opened the glue isn’t usable as it had glued shut, I know this because I went to use it to re glue the plants after a month.

Very strong hold and not visible in the tank
Wow - very impressive!!!! Most importantly it holds very strongly but also visually you can carely tell there's 2 prices glued together in the tank - it's not as obvious as other glues. Happy to recommend and will be using for the future.

This Seachem Reef Glue has become my go-to for mounting coral frags. The gel consistency is perfect — not runny like cheap super glue, and it gives you a few seconds of working time before setting. It bonds quickly underwater and holds strong, even with heavier frags or odd-shaped pieces. I’ve used it on both live rock and frag plugs, and it sets firm without clouding the water or irritating corals. The squeeze tube design makes it easy to control how much you apply, and it seals well so the tip doesn’t clog up between uses. Pro tip: dry the frag base and rock spot with a paper towel before applying for the best bond, and use a small dab at a time — a little goes a long way. Great product for any reef keeper who wants a reliable glue that actually works underwater.
