Methods and compositions for removing phosphate from swimming pool waters are disclosed. The compositions include both soluble and substantially insoluble lanthanide carboxylates, preferred examples being lanthanum glycolate and lactate. The methods include the addition of the lanthanide compounds to the bulk of the pool water, but preferably involve the loading of the pool filter with the composition and the circulation of pool water through the filter to effect the removal of dissolved phosphate in the water.
