Post SLAM x2 weeks - still cloudy blue

[skrupp2010]

Hi everyone. I did my first SLAM this year trying to open my above ground 24' x 54" pool w/ sand filter. My CYA ended up a bit too high but I've adjusted my chlorine level accordingly. Problem is that although the pool is now blue, it is cloudy and not clear. Levels are as follows:
FC: 12
CC: 0
pH: 7.4
TA: 150
CH: 210
CYA: 90

Any suggestions to get clear? I'm pretty new at all of this.

Your SLAM is not complete until:
1) Your water is clear,
2) You pass the overnight chlorine loss test by losing no more than 1 ppm overnight, and
3) Your CC is .5 or less.

Can you see the bottom of your pool or is the water so cloudy that it's opaque?

It might be time to add a little DE to that filter. If you reread the SLAM article, you'll probably find you missed it the first time around. Essentially what you'll be doing is the microscopic equivalent of setting window screen atop chicken wire. Just be sure that when you do it, you stick around the house, because it can load up really fast. Just backwash it away and add some more.
