Shame on you, Cecil! ;\) There's your scolding...

IF a person were to want to do such a thing, I believe they could take the organism they wished to kill and place it in five gallons of water, then incrementally add the sodium hypochlorite until death. An equation could then be derived, knowing the volume of water to be treated, to apply the exact right amount. That way they wouldn't risk applying too much.

Of course I would NEVER advocate such measures.

Holding a redear sunfish is like running with scissors.
