The purpose of this experiment was to determine if ocean acidification could be causing damage to stem cell processes in aquatic organisms based on what effect varying levels of aquatic pH could have on planarian regeneration. The procedures involved creating a system of regulating pH of water by connecting a CO2 tank, solenoid valve, and pH controller and attaching it with CO2-proof airline tubing to a ceramic diffuser in the water. 5MSF
