question for nano owners: When evaporation occurs, I top off with treated water, right? no salt in it. After maybe a half inch of evap, i top off with treated water and an hour later I check my salinity. and its higher than before. I dont get it. My salinity is swinging up AND down after topping off. I have a red sea hydrometer.
EDIT: ok this is weird. an hour ago SG was 1.026 and now its 1.014. my tank temp is 77 deg.
