What would cause my salinity to creep downward...I only replace the evap with freshwater. I am going to add some extra salty water to raise it back up and am curious as to where the salt is going.
Do you have a leak?
contrary to popular belief some salt is lost through evaporation. also salt creep. and also the acclimation process.
no leaksthat I know of!
salt creep is my guess too as I see there seems to be quite a bit of salt building up onthings. Thanks
Skimmate, I use a 1 gal container and when full I add 1 gal of salt mix back to the sump,
ya if you skim wetter you would lose a good amount of salt
First off what are you measuring salinity with and what are the reading s you are seeing?
From my experience, salt creep and skimmer are the primary cause of the slow drop in salinity. In the past, I have run smaller tanks without a skimmer, and I've never noticed the small drop in salinity, so skimming is probably a bigger contributor than salt creep.
