| Sorry to hear about your loss. We've all been through similar events so we know how this feels. I know from personal experience that PH crashes can be devastating. From you're description, however, I'm not sure what could've caused a crash. I'm assuming it didn't rain the night before and that no tap water was recently added to your pond. In my case, the PH crash was my own fault. Not sure what could've caused yours. JasPR might be onto something here. You should investigate other possible causes before simply assuming it was a PH crash. And no matter what you find out, obviously, you'll want to take precautions to prevent this from occuring again in the future.
