Case Study Description

Lisa Goldie, water quality researcher, at Hubbs SeaWorld Research Institute evaluated a 4000ppm C-Sense combined with a C-Sense logger.

The C-Sense and logger were placed in a small tank with White-Striped Sea Bass in order to record CO2 measurements in water every 10 minutes. A chemical was added to the fish tank, which would remove CO2 whenever the concentration was noticed to be too high. The C-Sense logger helped her to better understand whether or not this particular chemical was effectively removing the CO2 concentration in her tank.


The data demonstrated that CO2 concentration in her water did drop after the chemical was added, but the logger was able to provide data showing her that CO2 levels once again increased within a short period of time.  Knowing this now leaves them to consider whether or not they should spend the money and effort to add this chemical in the future.

“The CO2 C-Sense and logger were great, I loved them. This is a very valuable meter for my industry because low pH as a result of CO2 being respirated by the filters and fish is such a problem. I would recommend them to any intensive aquaculture facility in the world,” said Lisa Goldie with Hubbs SeaWorld Research Institute.
