Was my first time attacking aphasia and I only have it on that one piece of coral in the lfs wouldn't take it back.. I use the syringe but I guarantee you a Superman sprayed it between the ceramic plug and the coral.. I didn't see the aphasia for a long time but I did lose a section of the coral of the lemon juice touched I appreciate the tips and I will try tonightGotcha. What I do is lemon juice outside of the tank. Just remember to hold the aiptasia down hill from the coral. Then a little soft tooth brush scrubbing and a quick dip in a bowl of tank water to rinse. Won't hurt to swish it around quick then to the qt.
