Rated 4 out of 5 by mandiwarhol Best price, high quality
I use Magnesium chloride for myself not an aquarium! I soak in a magnesium chloride bath for pain control and this product works great! While its still unbelievably expensive, DFS has the best price for pharmaceutical quality crystals. I get the 5 gal buckets and have had no problems with shipping. Im very happy with this product, it it what it is advertised to be.

This item arrived with the cap off! Trying to remove it from the box caused a mess. There should be some kind of seal on this product.
