I seem to have an increase in salinity in my main tank recently. I recalibrated the refractometer with ro/di water and the result of my testing is 3.7% today in my main tank. It was 3.5% two weeks ago. I also had to adjust it from 3.8% to 3.5% back then.
Any idea why I get this increase?
I only add new saltwater at 3.5%, amino acids, kalkwasser for top-off prepared with ro/di water, ESV 2 Part system for alk and calcium, salifert trace elements for soft and hard corals and ESV strontium. I have added the same things for a long time and until recently I did not have issues with salinity.
