If I'm understanding it correctly according to his interview video with ReefDudes, it is. They recommend priming the system with CO2 scrubbed air, or air from outside pumped in and diffused through a wooden airstone, then inducing a controlled bacterial bloom of nitrifying bacteria. This supposedly stops the dinos from being able to photosynthesize due to the limited CO2.
Reducing CO2 is a historically somewhat effective plan, but carbon dosing adds a lot of CO2 and combining the methods may work, but unless the pH rises substantially, you are not starving them for CO2.
