Sudden Koi deaths after rain & thunderstorms
After a heavy rainfall with thunderstorms, all my 7 Kois suddenly died :hurt: . All had different sizes and ages, without previous signs of disease for at least 2 years. :crybaby:
Oxygen, ammonia, all NHx, pH and Hardness levels where in the normal range, even though a lot of rainwater fell inside my +100 gallon pond. Nearby contaminants? None that I could have seen or imagine of.
Since there where many nearby lightning strikes on the electric power lines (with power failure) , I suspect that some kind of current might have electrocuted my Kois through the water pump or UV filter.
Could this happen? :confused: Any opinions ? Similar cases?
I would really appreciate some opinions on what could have happened to my Kois, so I could try to avoid it before I start over again.
Thanks

I first suspected PH crash.
However Lee B, JR and Mr Pete all have valid points. I'm suspecting faulty wiring at this point. That ground fault breaker just wont work without a ground wire attached. I had a well pump blown completely off the 320' pipe in the bottom of my well during a sever electrical storm. The lighting actually hit a popular tree some 75 +or- feet away from the well but traveled the roots and then the well cassing then the water in the pipes to the pump exploding the hanging pump from the schedule 40 pipe. Lightening will travel routes least expected to get to your pond. Koi don't seem to take an electrical charge very well. Ph crash would have taken a few days to do your koi in. Hope you get it all back in line soon. ;) Mike
