And let's not forget KH guys & gals. Check your pH in the early AM & late
PM if there is much of a change you don't have enough buffering to keep
that pH from swinging, another stressor to fish. A KH test and a box of
baking soda is all you need to fix buffering. (That doesn't mean dump in a
whole box. It means test and report here. ;o) ~ jan
