KH should be a minimum of 40, with 80 being a better low end value, and may
go as high as 300. If your pH is 8, then I don't think is a KH problem.
Low KH is an indication of the impending pH crash with pH going down to 5
quickly which can kill fish.

Yes. Test pH and KH. It is possible you have experienced a pH crash,
and
the fish are swimming in some pretty acid water.
Thanks. I haven't tested KH yet, but I did test pH earlier and found that
it
is 8.0, which I understand is within the acceptable range. Can you tell
me
what the KH should be?
