I found this online:
As with calcium hydroxide, the effectiveness of lanthanum is greater the higher the phosphate concentration in the water, which means that lanthanum is particularly suitable for reducing a very high phosphate concentration, and less useful for lowering a slightly raised concentration to an ideal level or keeping it low via long-term application. That appears to remain the province of established phosphate adsorbers.
