I am still performing the SLAM procedure.

In the SLAM guide on TFP site, they recommend "Backwash or clean the filter as needed."

How would one know when it is "needed?"

When the pressure is 20-25% higher than clean, although it wouldn't hurt to do do it anyway
Have you done the overnight chlorine loss test (OCLT)

I didn't record the starting pressure when I last cleaned the filters about 1.5 months ago.

I started the OCLT test last night:
Night:
FC: 11.2
CI2: 0

Morning:
FC: 10.2
CI2: .2

It seems like my pool isn't getting clearer. I started the SLAM process in the afternoon of 11/11, so its been about 3 days. My starting SLAM FC was 11.8, keeping it up daily around goal of 12.

If you aren't swimming boost the FC up higher than 12

How much higher? The TFP SLAM website recommends for a CYA of 30, the goal SLAM FC is 12.

I have read that having a FC too high can damage pool equipment.

I am assuming with my filter that no matter how dirty it is, the water should get clearer, it's just that a dirty filter would take longer to clear the water.

You would have to go very high indeed to damage the pool equipment and most is damaged by low pH. So dont worry, a bit more chlorine means a faster result.

The measure of how good your system is, how quickly it clears up. Bad flow, low number of turnovers, high pressure readings and bad filtration media can all hamper the clearing. If you are not using a DE or cartridge filter you can add a clarifyer like Jolly gell or a flocculent.
I may not give you the answer you want to hear, but I will give an honest opinion of your situation as you decribe it.

I am going to keep at 12 FC and let it run for another 3-4 days and see what progress looks like.

Time is the one thing pool shops do not sell and sometimes its exactly what you need.

Gentlemen,

I have accomplished the goal after a month of diligently following the advice I received on this forum. I have my pool back, blue and crystal clear. :D :D :D When I started on this forum it was green and cloudy. And just in time for us hosting Thanksgiving (Tomorrow) so I don't have to listen to my brother-in-laws comments about how crappy my pool looks. :D

This morning I finished doing my last 3 SLAM checks and passed:
1. CC is 0.5 or lower
2. AND you pass an OCLT
3. AND pool water is crystal clear with no visible sign of algae (dead or alive) on floor and walls.

and I know how to properly use my K2006c testkit you recommended. No more using "guessstrips." I am no longer going to the pool store for advice, that was an expensive waste of time.

My advice to others who may be in my spot. Follow the advice on this forum and TFP website. Most important, have patience and be very consistent.

Thank you to:
