I just set up my aquarium and put in my Apex salinity probe with the salinity probe stabilization kit. It seems to be pretty stable but it is creeping up and up throughout the days. I have a ATO so any sort of evaporation should be accounted for and temp varies by 1 degree ( 77-78 ) . Any Ideas as to why it would be creeping up like this? I dont see a change on my refractometer (1.026)
thanks,
