I set up my paintball CO2 yesterday in my 10 gal with 3 amano shrimp. I'm using one of those cheap glass diffusers and from the looks of it, I'm getting 1 bubble every 2 seconds. My shrimp seemed okay before I added CO2, but I have noticed that they looked a bit more cloudy than their normal translucent appearance. Well, one died overnight, and another looks to be on the brink of death. What to do?
