I know Joe Y. who runs the amazing 20,000 tank and more at Atlantis Marine World uses it last I heard.

Noticed my comment on another thread?
Be aware that if you dose more Lanthanum chloride than you have PO4 for it to bind to, then it will bind to CO3 and precipitate out which will deplete alkalinity. Personally, I wouldn't be dosing Lanthanum into a tank, but I would definitely use Lanthanum for curing base rock or high PO4 live rock. Lanthanum will not be skimmed out, it has to be mechanically filtered out. It seems as though getting 100% of it out of a display tank setting is not possible and some people (including Randy Holmes-Farley) question what this precipitate will do over time if left in a tank.
