Wouldn't know.....Michigan reefer here.............I don't know off hand but the aluminium topic was brought up in this thread...I was just replying to it.......
The product EVERYONE recently found out that countained aluminium..Is baking POWDER....I'll post 1 link to 1 site....But there are many more I have found....If the "RAG" wants to go read them.....If you look more into the FOOD industries to find this out......Since they are more concerned with the HUMAN life a little more then CORALS....You will find out ONLY baking POWDER contains it.....NOT BAKING SODA......
There are lots of things that are considered fit for human consumption that one would never consider putting into an aquarium.
