Thank you. I have noticed that it does take a bit of freshwater, so I will just leave as is.Pretty much! It can take quite a bit of RO to dilute a 1.026 to 1.025. I run at 1.025 in my nano to deal with any fluctuations or equipment malfunctions of my ATO/sensor.
If you do not mind me asking, how many gallons is your nano?
