Maintaining salinity levels

[radone]

How do you compensate the water you loose if you skim wet.
What's the best way to add it back to your tank to maintain salinity levels?

I currently dose kalk but wonder how to add the salt back to the system to maintain my salinity

Thanks for any help

Auto top off system works great. Just add a little salt to the make-up water to compensate for the salt that is skimmed out.

The method I use is a 3 gallon tank next to my sump. I don't have plumbing anywhere near my tank so I have to fill the 3g tank every few days with RO/DI water. I add my kalk directly to the 3g of freshwater. There is a power head submersed in the 3g tank and it is connected to a float valve in my sump. I never have any fluctuations with my salinity but I still check it a few times a week.

I make compensations during water changes. I read the SG of the tank prior to a WC and if it's a bit low, I'll add enough extra salt water to prevent the ATO from kicking on for a day or so.
