I have 2 pm2's one for the display tank and one for the auto water change the one for the auto water change is in the New Saltwater bin. I need to find a chart for salinity difference between different temps. My temp in the basement is cold the nsw bin reads 63.5 and I do not want to heat the water cause I do 2 gallons a night no need to waste the energy. Any help would be great.
