My cat knocked over my DIY CO2 on my 20g long yesterday at some point... A
cup or so got venturid into the tank, which I discovered when I noticed
fish gasping at the surface. Other symptoms included a dead singapore wood
shrimp (damnit I loved that shrimp too) and bubbles coming out of the
gravel (!!! Oh god, when did this happen??)

I imediately did a massive water change complete with gravel vac (I churned
up probably 75% of the gravel), which seems to have helped a bit, and put
an empty airline tube in the venturi hole on the powerhead to help aspirate
some of the gases being formed.

This morning, the tank and it's denizens(6 or so pygmy gourami, 3
featherfin rainbows, 6 or so bumblebee gobies, some cories, a betta, and
algae control critters... and a baby singapore shrimp) look OK, aside from
water that is foggier than London on a cold morning.

Sigh.

Oh well, I guess I am on massive water changes for the next few days.
