Although most that responded to that thread thought it was electrical, I tested out my equipment and it seemed fine (still using it all without probs).
I'm still not convinced that I didn't release something into the water column, when I cleaned off the algae/cyano from the glass. The fish seemed to be affected within minutes, and also died "flared out"
Mouths were stretched wide open, and they almost seemed to be convulsing...
Anyways, I hope you get to the bottom of it!
