Just for curiosity sake - check the PH and hardness of the water in the pet
store (not in the bag when you get home)

The water in the bag comes from the same tank as the fish; the ph and
hardness wouldn't change during the journey home - would they?

Ph changes in the bag. Once its sealed and the fish eliminates in the
bag or just dissapates co2 etc through normal respiration it will
build up but as long as the bag is still sealed its relatively stable
for a period of time but once that bag is opened the ph can change
drastically.thats why you do not need to check the ph etc of "bagged"
water...........get a sample of the lfs water to compare with, that
has not been sealed up with a fish. ON top of that.you can take a
sample of water.and carry it home or just let it set there for an hour
and it can change PH......thats why its a freaking joke when lfs ask
for water samples and the first thing they check is the PH. Ph can
change from morning to night and it can vary due to amount of
ventilation a house has.
