If I remember correctly, you live in my area and we have nightmarishly unpredictable water. There's been an algal bloom in the Ohio River in our area the past couple days that's been causing some problems, as well. So it could definitely be a water issue.
Have you tested parameters?
Haven't done a parameters check yet. I literally did this post on my phone while waiting in a doctors office. I'll see whats up.
