At what rate does water evaporate?
How fast/slow does SW evaporate?
When is the best time to replace evaporated water? How much? I have a 56g column tank. 24in height 30in wide 18in deep Should I make a line mark on the tank to know when to replace water?

Yes make a line and fill it back with ro/di water

You should look into getting an automatic top-off. In the mean time, make the line and check it daily. Make sure you have everything running first as the water will rise/fall as you turn on different equipment.

Evaporation rates will very greatly depending on many different factors. So its hard to just give you a rate of evaporation. The best way to measure it is like you said. Make a line and see how much needs to be added after a given amount of time. Its best to keep the water level as stable as possible. This keeps your salinity more consistent, and also if you're running a skimmer a constant water level will make that run more consistent.

Another note you need to be topping off with fresh water. The salt in saltwater doesn't evaporate so adding salt water for top off will raise your salinity. |

Do you have a sump? If so, make your water line mark in the sump and add fresh water to the sump to that level. I use a piece of tape on the outside of my sump and add water at least twice a day in summer because it evaporates more when the cooling fans are on; once a day in winter.
