At the End of My Rope

[Earthgirl]

I"m at the end of my rope folks!!!
The darn Aipstasia battle!
I've lemon juiced it
I've started Torching it last night
And the F*@#ing bastards keep coming back
The salt is fine
Everything is fine, I just can't kill them!!
I have a 55 gallon with the 2 peppermint shrimp and of course some hermits
Should I get more?
I have never been so frustrated in my life with a tank before and I did have before a 230 gallon with stingrays that I had trained to eat worms out of my hand!
Please
Please
Please help!
what do I do next?
