top off???

It depends on the SG of the water in the tank. If it's low, we mix salt water. If it's on the high end, we use RO.
 
For strictly evaporation top off, always use RO. For water that has been physically removed (skimmer, WC, etc), use the salt, but test your SG first!
 
Ro water is typically used if you you are replacing evaporated water.Evaporation only takes the h20 and leaves the salt behind.
