Yes. It will remove the suspended po4 in the water column, (reason for sock). The longer the dwell time the more removed, (a reason for dripping). As stated above, it can be harmful to livestock if po4 is reduced to fast. The lanthanum chloride that passes thru the sock can also harm your livestock,(a reason for dripping).

There is no set formula I know of. It really depends on how high your po4 is to start with. Go slow. Test. Nothing good happens fast. You use it to drop your po4 level to a manageable level. Once reduced, it is better to use GFO or other means to get it down to near 0.
These are my experiences and your results may vary
