Looks like I should pay more attention to my ph controller. My ph was 6.6, and I cleaned the electrode tonight. Then I put it in the calibration solution, and it was at 7.3. So I calibrated it back to 7.0. Then I checked it in distilled white vinegar, 2.8, perfect, no adjustment needed. Then I shook it off, rinsed in water, and placed in the tank. Ph is 5.8. Ouch. That puts my CO2 at 214ppm. Is this for real? My ph is now slowly rising back to the 6.5-6.7 range now. I didn't expect it to be off that much.
