Unfortunately there are not proper directions on the bag/bucket to instruct anyone to achieve a salinity of 1.022. As a matter of fact, the directions are not specific as to which salinity you will achieve. It simply tells you to add 1/2 cup of Instant Ocean Sea Salt Mix per Gallon of water.
I have finally diluted my aquarium water down to the salinity of 1.022 and I want to keep it that way. So, when I am ready to do a water change, I nee to be able to mix the solution to the exact salinity. So, I ask again. Does anyone know what amount of salt I would need to mix with 5 gallons of water to reach a 1.022 salinity? Is there a certain formula that can be used?
