I used lanthanum chloride to lower phoshates in my system after I trusted someone that the Pukani Rock I added to my system was cured. It wasn't and I also spent about 2 years getting the system back in shape. Get a tester (I like the Hanna ULR tester) and see what's happening. No need to waste money unless the phosphates are there
