Not at all. your fish are gasping but not dead so you know what the DC would say!!!
Too high - yellow. Just need to get it down a little so that it reaches lime green and your fish will tell you this. they will get back to business.
Many people use the DC at the beginning and after that tend to watch the fish and plants for signs of CO2 to high or low. Mostly a confidence thing. Daring to push it as high as possible with the confidence you aren't going to do any damage.
