This may be a stupid question, but even after two years doing saltwater tanks I never really thought about it. Does skimmate have salt in it? Or is it just water that your ATO will replace?

I guess I should be more specific. I didnt know if the salt stayed in the tank, and the water pushed into the collection cup is basically salt less.

I asked this same question myself only yesterday.
The answer is it pulls salt+water from your tank, and the ATO will refill it. However compared to the overall volume of the typical tank and daily evaporation, it's a very small amount that can be compensated for quite easily with regular salinity checks and top ups, frequency depending on how wet you are skimming.

Gotcha! makes sense. I got my new RSK 600 yesterday and I randomly was laying in bed this morning at 4am thinking bout this. lol

Yeah, I assumed it would just be foam pulled out, but when water started coming over, I had the same thought. I have a relatively light bioload, so I plan to skim fairly dry to avoid it as much as possible.
