You can get a drop checker for next to nothing. There's really no reason to run it by "guessing".

The last time I had a bad overdose, mine were all gasping at the top and the cories were turning circles....but only lost one panda cory, so everything turned out almost fine. ;)

Gasping fish and dead inverts is a damn good sign of overdosing CO2. Inverts are the first to go in my experience.

I had this very same trouble 4 months ago.:) Lost one blue ram and a shrimp. In this case, check your CO2 level and rectify it. Along with it, switch on airpumps to increase oxygenation and do a large water change. It helped prevented more casualties.
