Dang V! There is a scientist in the house! That did help and was just what I needed. Thanks.

Sas, I have read in other articles as well that the pharmacy bottles of Iron will last forever. Many use it, including Randy when he wrote the article. I didn't think the Flourish was chelated since it seemed to be more specifically for fresh water plants after further investigation on the seachem site. Kent makes a product that is chelated but also included manganese which Randy mentions by brand as one he doesn't like, but that may not mean it is bad. I am going to Rite-Aide today and look at the supplements counter. I will let you know what I find.
