what i use is lemon juice, i take a syringe and pull in about 1cc of
lemon juice and give them a dose internally. ya gotta be quick. dont
squeeze out more than 1/10th of that cc, usually it takes about 1/20th
of a cc, if you get it inside them. then you can stab the rest of
them until your cc is gone. if you have good alkalinity it will
buffer the acid. the tank shoudl be able to handle the additional
organics and process them, and its a relatively safe method.

I didn't try lemon juice, but I couldn't get calcium to work.

also, i fully agree with pszemol, natural biological control is always
better than chemical control, in ANY circumstance, human or fish. but

Agreed, when it works. When it doesn't...

p.s. i wonder if you tried to use a syringe for your product if it
would reduce surrounding carnage

That's the plan for today; I'll use them on the smaller buggers.
