gotta check those perimeters

[qasimja]

Im not sure how this happened i guess because of salt creep over the years but my salinity dropped to 1.019 i haven't checked it in over a year i turned off my ato and over the next few days i will add saltwater mixed at 1.040 to top off til i get it back up i have 175G total water volume in this display so this might take a few days

It has happened to me a several times over the course of the last 3-4 years.

thays why I have the tropic Marin hydrometer, milwaukee refractometer, and vivid SPS kit for checking salinity

(Ps, the dip in salinity is due to me doing water change)
