vinegar or lemon juice for aiptasia

[gummi]

Ok - I'm losing the aiptasia battle.

Joe's Juice - they wilt for a few days and come back
Inject with Vinegar - they seemed to multiply!

Now I'm considering using hot water with a mixture of either lemon juice and/or vinegar.

My question is which is safer for the aquarium? I am going to turn off my powerheads tonight and do my experiement but since I'll be treating a fair amount of aiptasia, which is safer?

I'm going to do probably 1 part of lemon juice to very hot or boiling water.

Any advise or other methods? I added 2 peppermint shrimp but there's no way they can tackle the bulk... i need to do something.
