That could allow for some significant salinity fluctuations depending on the size of the sump/compartment the sensor is in. What I like about the Tunze is the precision.

It depends on your sump for sure, an inch in my sump is about 6.25g in a 330g system. I like that it doesn't cycle the RO/DI to the top up barrel too often and I still can't (knock on wood) get over how reliable it's been.
