2013-8-29 accidental formalin (Rid-Ich) overdose

Formalin OD

Accidentally added 9 TBSP to 90 gallon tank instead of 9 TSP!

 

See the ORP (redline) crash.  Tank became hypoxic.  Fish at surface gasping for air.  Did 50% water change ASAP and added airlines ASAP.  I think all the discus were saved.  Lost one rummy nose tetra.
