377 ppm of CO2!
(KH=5 with pH=5.6)

Most all of my cherry red shrimp died in this accidental CO2 increase. The babies survived by bunching together very close to the surface.

Lesson learned: Make sure you see and can count your bubbles!

Ah, the plants - anubias and glosso - pearled like crazy. The undersides of most Anubias leaves, even the ones in partial shadow were covered with bubbles.

I shut off the CO2 and started bubbling air in the tank. The shrimp started to act normal at pH=6.4. I found it rather strange that the pH climed very slowly up - going from 5.6 to 6.5 took about 12 hours (tank is only 25 gals). It may be the EcoComplete or peat underneath that caused that.
