Just got cardinal tetras..acclimating them with co2 tank.
I have a 20 Long planted tank..... drip acclimated my cardinal tetras, and pu tthem in.. They were in for an hour. then I turned off the lights. (bed time) bought them at night. My yeast sugar co2 runs when the lights are on. then at night, I turn it off, and turn air pump with airstone on. I know cardinals are sensitive to PH swings.. what should I do? I have left the co2 running in the dark for an hour now.didn;t want to turn it off so soon. sould I run both?
I have rcs and otos in there too. for what it's worth. Thanks.
