i do not understand.
if you are topping off with saltwater then i see why the
salinity is sky rocketing, but other than that ... there is no way it can.
if you top off with saltwater the
salinity will rise because only the water evaporates, not the salt in the water. when you add more SALT water ... it is like adding 1.025 to 1.025 without removing any of the old SALT. so that would raise the
salinity dramaticly in a nano.
if you top off with straight
RO/DI water then you are just keeping the
salinity at the same level, because you are not adding salt, but adding water to keep everything balanced. because the salt does not evaporate. when the evaporated water leaves the tank ... it leaves the salt and causes a rise in
salinity because there is less water in the tank and the same amount of salt.
i hope that does not sound to confusing.
