| Lost my whole school today
Yesterday I noticed the koi were a little sluggish and weren't their usual glutton selves. I tested the water and everything looked fine. I assumed it was the heat and just looked in on them every now and again. A storm rolled in later in the day and I could see the koi coming to the top. I thought they were cooling off and it was good to see them active. I stopped worrying and went out to dinner. This morning I woke up and every fish in the pond is dead, the Ph level seems to have tanked. I just dont know what could have caused such a drastic change in ph levels.
Any clues?
