Using different adhesive products to fix new corals to the live rock can sometimes be a pain. You’ve spent the last couple of hours acclimating and you just want to put them into the aquarium. You could try wedging the corals into the rock work, hoping they’ll stay, but more often than not they will fall over because of the water current or a careless fish. Because of this, using an aquarium safe epoxy or glue is almost a must. These products will secure the coral to the rocks just long enough for them to actually encrust onto the rock and form a more permanent locale in your aquarium.
