Aquarium Advice Apprentice
I have mixed up 4gal of saltwater twice now. I made it according to the directions of 1/2 cup to a gal of RO/DI water and both times it can out at 1.033 @ 78deg. According to the instructions it says it should come out to 1.021. I am adjusting it to 1.025 but am I doing something wrong?
