I have watched a ton of ted talks, I find them super entertaining and enjoy the info given. I came across a short one that I feel many of us reefers could easily relate to. Imagine if you could extract and reuse the Ca, K, Mg from your WC water to help boost these same element at a later time. Also makes you wonder what would happen to your reef tank if these bacteria somehow made their way in to our tanks.
