Re: V3 #18 Killing daphnia with "Amquel" question

I first noticed this problem as I would find daphnia, moina dead in tanks
that I had recently cleaned. Of course I added AmQuel as there are times of
the year that chlorine and cholramines are added to our tap water.  I
noticed daphnia kills up to a week or so after each cleaning.  Not too sure
if it persists longer.  I only put it together when I sent a shipment of
monia to Jim Eller, and figured add some buffer, some amquel (it works for
fishes) and they all died enroute.  Doing side by side (in same shipping
bags) I found that the amquel was the cause.   I suspect that most
daphniaand moina are fairly susceptable to certain water contaminants and
as I am not sure what are the active agents in amquel I can't say for
sure...
