Can lanthium chloride be used in the display tank? I used it to cure my Pukani rocks before I put them in my new tank but I have Green Hair Algae now and thought I read that someone used it but not sure. Bubba</em>
What I have read is that yes, it can be dosed into a display tank very slowly. Most who dosed it into a display tank dosed it into a very fine filter sock and then washed out the parcipitate.
