Hey guys, one of my buddies has been using Lanthanum Chloride for a few years to keep phosphates at bay. He drips it into a filter sock slowly because it precipitates and the sock clogs quite fast. He also mentioned that Lanthanum Chloride lowers Alkalinity so to test after dosing. Has anyone tried using it and can you provide feedback and/or comments? Thanks.
