reef Posted March 2, 2006 Report Share Posted March 2, 2006 It can be used to remove orthophosphate. any thoughts Layton?? Quote Link to comment Share on other sites More sharing options...
Feelers Posted March 2, 2006 Report Share Posted March 2, 2006 "Lanthanum carbonate was approved as a medication (Fosrenol®, Shire Pharmaceuticals) to absorb excess phosphate in cases of end-stage renal failure." Apparantly its pretty safe, I imagine it's not cheap Quote Link to comment Share on other sites More sharing options...
lduncan Posted March 2, 2006 Report Share Posted March 2, 2006 All I know about Lanthanum is that it's used in glass coatings in lenses and stuff. I'll have a look around see if I can find out more about it. But if all it does is bind orthophosphate, then I don't see much point, you still have to get it out of the tank. Being a chloride, i'm guessing that it's pretty soluble in water. I'd say that the usual iron or aluminium phosphate removers are going to be cheaper and just as effective at binding orthophosphate.

lduncan Posted March 3, 2006 Report Share Posted March 3, 2006 I've had a look around, and it looks like all is related to human's in terms of a particular drug. One thing which would strike me first is that the pH in a tank is substantially different to parts of the body. pH can effect these sorts of binding properties, so I don't know even whether it would be effective in a tank or not. Second, I have confirmed that lanthanum chloride is soluble (as I suspected), which means that all it has the potential to do is bind phosphate. It can't remove it from the system. Then there may be potential toxicity problems to corals and fish too. Cost: around $35 USD for 50 grams Layton Quote Link to comment Share on other sites More sharing options...
