Well, a little more detail would help us help you.

Please provide details of the pool.

When you say you have SLAMed for a week, tell us what you have done and how often?

What test kit are you using?

What products have you put in the pool?

Im using the taylor test kit recommended by trouble free pool,im using liquid chlorine 12.5%, checking readings multiple times daily, Ive passed the overnight test multiple days in a row

If you have passed Overnight Chlorine Loss Test and have "0" CC then it can be time to add DE to a sand filter to help clear the water a little quicker. Instead of actual,DE powder, I use cellulose fiber DE replacement powder.

+1 what tim said... keep vacuuming and brushing, and keep your pump running until it's clear.

The "milk" is dead algae, to remove it requires filtration.

As your filter works to clear it, you will find yourself having to backwash a bit more than usual, (the dead algae will collect in your filter).

Well im having to backwash less.

The pressure isnt going up for the need to backwash, i even followed instructions to add de. No luck. Im only having to backwash every 2 days

You have to give it time. In less than an hour after being told to add DE you are complaining that it isn't working

If you are having to backwash every two days that proves it is filtering the stuff out.

I have been adding dE after each backwash for 5 days now. Im not sure why you thought I just learned this and complained it wasnt working after an hour...confused yes...but anyway There is no improvement. I backwash every 2 days because Im at 10 psi and I clear it when it rises to 13. 2 psi over 2 days leads me to believe its a filtration problem

Have you been taking pictures along the way? If so go ahead and post them. If not, take a few of stuff like stairs and ladders and post them.

Nowhere in any of your posts do you mention already using DE in your filter, hence why it looked like you only gave it an hour.

Is there anything else you have added but not mentioned?

Well...ive given this a few more days and still cloudy. So yesterday flocked and now im crystal clear. I had my sand replaced yesterday, which was the problem behind my cloudy pool. Long story short, slamming ur pool will NOT cure a cloudy pool if your filter is not working properly.
