I am not really propagating but I am rescuing a mushroom I have. It gets swept by the currents to the back of the tank where ther is very little light. Now I have gotten the mushroom to the point of bonding to the rock chips in my aquarium but when I go to glue it to the bigger piece of LR the mushroom detatches itself. I know its detaching itself because the chips of rock it had bonded with are still stuck on the LR. What am I doing wrong? I am using super glue as instructions say to use.
