Corals not glueing to live rock

[shakacuz]

This usually works for me.. First put some superglue on a skewer or ur finger and rub it on the spot where you plan to put your frag. Then try gluing the frag on that spot. It helps the glue stick together better in my experience.

this is what i do. if i cannot get a skewer or something to put the glue on the rock with, then i apply an extra dab of glue on the frag, place it where i want it and wiggle it around, lift it, then press it down. this tends to smear some glue on the rock and also exposing the inside glue that ha snot touched the water for a tighter seal.

You need to move the frag around a bit or twist it to break the outer film on the superglue. Also, if I'm gluing underwater, I will take my long tweezers and really mash the edges of the glue down into the rock.
It's one of those things you get better at over time.

I use seachem brand coral glue. Not sure how safe dollar tree glue would be. It may contain toxins and probably isn’t designed to adhere well in water

Super Glue or Loctite brand cyanoacrylate gel is completely reef safe (the company that owns the patent for cyanoacrylate owns both of those brands). Seachem brand is identical to the dollar store glue and doesn’t work any better. If it gives you peace of mind spending more for an aquarium branded product, that’s fine, but you’re really not getting a better or safer product.

Bump the seachem

A sandwich of superglue gel- 2 part epoxy (I use JB waterweld)- superglue gel. I will never go back to just superglue.

People need to be careful when utilising things which are not inherently marketed as aquarium safe.
The JB weld product you mention I just looked up to purchase and it states it is safe for potable water containers which I then thought ‘ok that’s good enough right…?’ Then saw further down “toxic to aquatic life with lasting effects”.
So I will not be using this! Just a bit of a warning to others to check and make decisions based on their own research not just blindly go with what others have done :)
