Kristy,

Keep in mind that there have been some changes to the dowflake that Randy recommended when writing that article, apparently there is now more bromide in the product and its long term affects to reef tanks are unknown at this point. You can find more info here:

and

If you choose to start using the recipe you might want to consider ordering from someplace like http://www.bulkreefsupply.com/.

Good luck!
