Is 1.022 really that low anyway. I use the recommended dosage on the label of my reef crystals...1/2 cup per gallon, and I get a SG
right between 1.021 and 1.022. Furthermore, my hydrometer, as well as others that I have seen, have a "highlighted" zone that you should be trying to get the needle to fall into. That zone is from 1.020 - 1.023. According to my devices, and recommended dosage 1.025 is actually too high...now, I know that this is not the case. I'm perfectly satisfied with where my SG
is at and don't plan on changing it...just wondering why, in an enviroment as sensitive as a saltwater aquarium, is there such a gap in what is considered "best".
