Greetings everyone, I am new to reef tanks and just finished my second water change on the tank which is a month old and quick cycled with live rock and sand and Dr. Tims. There are 2 fish in the tank. My tank salinity was 1.026 and I changed out 10 gallon of water which was pre mixed and heated 24 hours i advance. I zeroed my refractometer and checked the new water and it was 1.026. I changed out the 10 gallons and now my salinity in the tank reads 1.022 / 3. I am wondering why the level dropped? I know my new skimmer has been running pretty wet with about 1/2 cup of water every day or two. Over a 2 week period will that change my salinity level? it is being replaced with my ATO which is RODI water and I know the salt is supposed to remain in the tank during evaporation. Is the cup from the skimmer causing the fluctuation?
Thanks for any help in advance.....I certainly need it.
