So i have a little salt creep built on the side of the outside of my tank. And i was just making sure that my salt level is decreasing because of the salt creep right? kinda wierd qustion
Not really yes you will loose some salt but due to evaporation of water your salt level will go up if not topped off properly. Just keep an eye on your levels with a refractometer.
It is salt, but a very minuscule amount. If you test your salinity at least once a week you will be able to correct any problems (which is more likely to be cause by something other than salt creep).
