Aquascape Tips for CO2 injection

With the risk of oversimplification, a good starting target would be attaining CO2 in the region of 20ppm -35ppm. If using a bubble counter - start at one bubble per second per 20 gallons of tank volume, then slowly tune upwards while measuring the pH drop. (It can take a few hours for the pH to drop fully and stabilize).

Is too much CO2 no good?

Signs that CO2 saturation is too high:

Lowered Activity: Fish that are usually active hide or are less active, sluggish, signs of labored breathing, delayed reaction time in feeding.

Position Change: Fish change their natural positions to favour positions closer to top of tank level or towards high flow areas. Even snails and shrimp will hang out near top of the tank though it is not a natural position for them.

Waterline breach: Snails/shrimps try to breach the water-line.

Decreased brood rates: Applies to CRS and sensitive shrimp

Erratic behavior: Fish showing erratic behaviour and/or gasping at surface are very severe signs; water change or rapid aeration should be done to immediately slower CO2 levels.
