Just picked up my first box of this. I'm switching from Salinity. Do I need to worry about mixing/shaking it like my bucket of Salinity to ensure the salts are mixed properly before using? I'm planning on transferring it from the box to my empty bucket, but I'm not sure if it will all fit, so I don't want to have different ratios of salt in the bucket and whats left over in the box. Anyone see issues with this?
