Scott, right before i left Turkey, i drained all the tanks.
Because when you and i talked about shipping fish eggs, that made sense and Keith and i were even talking about not going to Texas at all. My wife was little pissed with me because that water was stinky. So i drained them all.
That's the story...
I read some articles online and they say GH is not something to worry now. PH is not super high too.
I changed 30% water today and used an ammonia reducer in that tank. I don't think it is too late to save the fish. If they were dying because of high ammonia fish deaths should stop soon.
Nitrite and nitrate levels were close to 0 in that tank.
