Mmmm... Maybe. But they do say that one should not worry about the pH getting too low in the reactor and consequently taking down the pH of the tank down because (so they say) the pH of saltwater CANNOT drop below 6,5. They also mention that if the probe in the reactor reads below 6,5 it means it's wrong and should be recalibrated.
I went to my LFS Friday and saw the Schuran reactor. It was not in operation. However I could see big differences in the design and one of these was that CO2 does not enter the reactor through the pump. So I tend to believe the seller when he says that this model wont produce the noise the Korallin reactor is producing.
