Anyone know how much Lanthium Chloride is in a typical phosphate remover ?

I don't think there's any. I could be wrong, but that may be used in chlorinated pools.
The ceramic types like Kent are aluminum based, and Phosban/ROWAphos are granulated ferric oxide.

I am pretty sure Atlantis Marine World Aquarium uses Lanthium Chloride to help control PO4 levels. I am not sure if there is any Lanthium in the commercially available aquarium products, as stated above they are either Aluminum or Ferric Oxide based.
I know a few members in the club were going to experiment with Lanthium Chloride, but I don't remember seeing anything else posted such as their experiences with it.

Yes, Atlantis does use it, but I recently learned that they use it differently than most hobbyists, and I consider the difference potentially important. They dose it just before a sand filter. So any solid lanthanum phosphate and other lanthanum solids that form are removed. That is different, and better, IMO, than simple dosing to the tank where it just mostly settles out somewhere.
There are some hobby brands around, and I think they are liquids you dose and not solid lanthanum carbonate, but I prefer GFO.

To be clear, the product that Atlantis and other large public aquaria use is Lanthanum chloride, in a liquid form. In tank water it forms a precipitate with phosphate, and also to some extent with carbonate.
I think it quite likely that the liquid phosphate removers in the hobby are in fact a dilute form of Lanthanum chloride, but I do not know the concentration. The swimming pool version of Lanthanum chloride lists pretty clearly what amount of the product is required to remove whatever level of phosphate you want to remove. I've yet to experiment with the stuff, but I agree with Randy, it's probably a good idea to be physically removing the Lanthanum phosphate (with a filter after it forms) from the water.
