I have been trying to figure out the correct amount of salt to add to my five gallon bottles when I do a water change. If I follow the info on the red sea package, I achieve only 1.010, not nearly the 1.025 that the pamphlet says I should get. I even let the water sit for one week and still not there. The recommendation is 1.6 lbs per five gallons, but I find I must add at least two pounds! I have calibrated my postal scale, and it is accurate, and I am using a refractometer, which I have also calibrated. Are the instructions just wrong? Or am I doing something wrong? I want to run the tank at 1.024.
Thanks for any help you can give.
