I buy my glue at a hobby shop...That way I get a much larger container for a great price. Depending on the coral being glued, if it is real slimey, like colt, or xenia, you may need to use some bridal veil or similar item to help hold the frag in place vs. using glue by itself. Also, I've had a tough time with some leathers because as they expand and shrink they work themselves out of the glue...once again, you can use the veil, or use a needle and fishing line to attach to a piece of LR. Happy reefing!
