What steps do you guys take when you top off your tanks in between water changes? How do you keep the SG in check when dealing with evaporation?

The salt doesn't evaporate...just the water; as the water evaporates, all the salt is left behind. So, as water evaporates, your SG rises. If you just top off with water (preferably RO or RO/DI), your SG will remain the same. The only time you really need to worry about matching SG is when you do water changes.

HTH! :)
