It will be awhile before I know if it is a good long term preservative for water storage, but it does a great job on the Berkeys for keeping the water fresh and keeping scale down. Found myself having to clean out the top of the Berkey at least once a week; the water would start to taste a little brackish and stale. Since using this, there’s been no such problem. Each container has A LOT of product and is very long lasting. Have a new neighbor who is also a fan of the Berkey and happily uses the product for the same reason.
