salanity raises??

Does anyone else get this? I alway start out in normal to low ranges and it ends up high after a couple of months.

Do you top off the tank with fresh water between doing water changes (to compensate for evaporation)?
If you do not add fresh water for evaporation, the problem will exist. You could also add less salt when doing the water changes to compensate for the evaporation.

I use less salt b/w changes but don't add fresh water thanks for the advice.
