I guess I am not sure my water softner broke about 8 months after I bought my home and I have never bothered with it again??????
I hunt on 1029 acres and we have 6 mineral licks I personally do the following
1-50lbs bag of di-calcium phospahate 1-50 bag of trace minerals 1- brown mineral bloack on top 1-small bag of deer cain one time for an attractant.
I dig a small hole pour in the di-cal and trace minerals with 1/2 bag of deer cain. stir well with the dirt I dug out and the pour deer cain on top then I place the block on top of the filled in hole.
deer antler is 2/3 calcium and the next big mineral is phosphate. Deer hit these all year long even in freezing temps.
