thanks for the response.

Adding a bag of freshly activated carbon to the mix probably sucked all your
oxygen out of the water, you need to pre-soak this stuff b4 use. Do you have
a waterfall? Hows your surface agitation? Your water parameters sound fine
(how old are your test kits?) so oxygen depletion is the only thing that
springs to mind.

carbon was well rinsed and soaked (in ro/di water) for about an hour
as i do with all carbon additions. the kill started before i did this.
the remaining two are swimming fine after the addition. i know the
carbon didn't do it.

for aeration, i have the pump discharge going to a venturi and using
an urn for a return (about 1 foot fall).

test kits are reliable.
