Well I just got a better diffuser (GLA atomizer) which blows around the tank without any bubbles. The bubble count was high because it was not getting diffused enough now it's at about... 1-1.5. CO2 is stable at 30ppm (GLA drop checker). I'm trying to get in touch with the water treatment plant in my town to figure out the GH of my tap water. I found two shrimp molts in my tank this morning but no bodies which is a good sign. PH is 7. I have a feeling that if the water is soft then the calcium is the culprit.
