| Don, you could be right on or you could be making a sweeping error based on the words of Veronica's assumptions. It has been my experience that most hobbyists that loose ponds in a dramatic way begin by suggested that everything was normal and the water was fine before the event. And that could be very true, especially in the case of a pH crash. But 'marrying' a theory early on can be like putting on blinders to the big picture.
A good detective remains uncommitted and dispassionate about theories until the evidence points in a definite direction. And in many cases, getting a diagnosis is as much about eliminating what the problem 'wasn't'.
So in my opinion this problem could be:
) a pH crash
2) a poisoning from natural or un-natural sources
3) suffication
4) a dynamic of disease and environment
Collecting data and history is the best way of eliminating some of these theories and bolstering one over all. - IMHO JR |
