I’m not sure if this is the right area to post this question. But does anyone know if Fauna Marin’s Pro salt is a good salt for auto water changes? I have a very large air stone in my 5 gallon reservoir to help keep the water fresh. The container only lasts roughly 6-7 days until I refill it with new saltwater so it doesn’t sit too terribly long. Anyone know if that salt mix stores well for those 6-7 days?
