Yes, when you physically remove water from your tank you also remove salt since it is dissolved in the water. You need to top off with ro
water for anything that evaporates as you only use pure water this way and no salt. If you top off with saltwater you will end up with a too high salinity. About the foam, not sure. Did you mix the saltwater in the tank? Also, did you add the stuff to remove chlorine from the tapwater?
