Thanks for your reponses,
There were days last months extremely hot. I had the fan blowing in my 35 gallon tank to keep the temp down; resulting large amount of evaporation and increasing in the salinity. Fortunately, I was off work for those days and actively and manually top off with fresh water.
In the future, i might not be too lucky when I am at work. The salinity will creep up more than .002 .
Have you guys ever heard of large change in salinity the tank causing the corals and fishes to die?
