We really like to know what you are dumping in your pool. I hope your are cleaning your filter often, that is the best way to get suspended particulates out of the water. Clarifies just clump the particulates so the fall to the bottom. Most of the time it ends up in the filter anyway.
Yes, that is it.
Please understand, the pool did not turn into milk because I put so many chemicals into the pool. It turned into milk because I put just one chemical in. I put in a iron/metal remover to get rid of extensive staining. As soon as I put it in, the pool went from clear to pure milk. I could not even see the first step. That did its thing for a few days and the staining indeed went completely away. The surface is now back to its normal look. Unfortunately the phosphate levels went through the roof, because the iron/stain remover is a phosphate based chemicals. After using it, I have had a bear of a time getting the pool water clear again. That's when I started using different products to try to clear the water. I am 75-80% of the way there now, after 11 days of using the clarifier and washing out the filter 3 to 4 times a day.
I added a photo to show where I am at today. Not perfect yet, but I have made a lot of progress from looking like a gallon of milk looks.
