lowest I can take my salinity down?

[saltyESQ]

I am treating for ich and my salinity is at .09

the problem is that it moves up to .10 everyday due to evaporation. I was wondering what is the lowest I can take it down to make sure it remains at .09 or under.

It's good where it is.

The most you need to lower the salinity is 12 ppt. 14 ppt is a good "safe zone" but never let it get to/above 16 ppt.
