Plant Safe glue?

super glue GEL works fine... and will set under water

ONLY THE GEL THO!!

or you can go to the salty store.. and get some of that Reef Ice stuff
 
Agree.. super glue GEL works perfectly and won't harm anything. I've used it myself, as well.

When it sets in water, it turns white. So be careful where you apply it.
