I drop it directly into my sump. Chamber right before the return pump. No filter sock. It does turn the water a bit cloudy for a few minutes but clears up in about an hour. Use with caution if you have tangs tho.It’s Lanthanum Chloride and definitely works. Some reefers like it because it’s predictable. It will bind to phosphates in an exact amount (as long as the phosphate is available), but be sure you take care of the flocculant that is formed. Many people drop lanthanum chloride directly into skimmer or into a filter sock.
Many other manufacturers have a lanthanum chloride product (e.g., Brightwell Phosphate-e, two little fishies Phosban-L).
