Chemical Balance questions

[BigTallGuy]

Thanks. I am also in Mesa. My salt levels have been declining around 20-40 ppm per day. I also run a water feature and have seen that aeration can deplete salt, but do not know if this is true.

In our neck of the woods, water features will loose alot of water through evaporation, but as Waterbear says, you will not loose salt. You haven't mention what the source of your leak was nor what you did to fix it. How do you calibrate your Salt tester and how often?
