Hi all, I am new here. I have a 300 gallon heavily planted tank with a pressurized CO2 system. I accordance with my pH and KH my CO2 is running at 38ppm. I have 10 Blue Rams, 50 Bolivian Rams, 7 Cockatoos and 3 Borellis as well as many other fish, shrimp and Snails. The Rams and Apistos show no signs of stress at all.
