Reef Salt Storage

[puckett26]

I have began a slow migration over to AF products. Prior to this I utilized automatic water changes. 5 gallons over the course of a week. Can I store 5 gallons a week of the Reef Salt mix if I put some type of circulation in the storage container? I understand that the directions recommend immediate use but I would really like to keep my auto changes going if I can. Any help would be appreciated.

The most important thing to storage this premade saltwater is to be airtight.
