Aptasia

[safety4fire]

My tank has alot of aptasia in it. I think I will get some needles from my brother inlaw, as he works out alot and should have some
I have heard that if you inject lemon juice into the aptasia it will kill it.
I have tried Joes Juice, and apart from turning them a pail color, it does nothing. Some of these aptasia are getting big. Can someone tell me how big they can get????
