hi all got a dumb question i have a 180 tank my question is on the reserve water in other words my ato holding water do i use fresh water or salt water?

Fresh water (RODI) for top off. The salt doesn't evaporate with he water. Use the salt water for water changes.

Fresh water, youre replacing water thats been evaporated. If you were to fill your ato reservoir with saltwater, it would increase your salinity.
