SLAM help

[Kimsports]

How often are you testing FC and adding chlorine to get your FC back up to SLAM level?

Have you removed the ladder and cleaned it? Even inside the tubes with a brush? If not, do that.

Do you have a light? Have you removed it and scrubbed behind the light? If not, do that.

Did you check and scrub the skimmers? Did you check the weir doors for algae? If not, do that.

I test FC at 6 AM and 9:00 PM if not more every day. Ladder is out. Skimmer and weir doors scrubbed. Is it safe for me to unscrew the scres holding in lights myself? My pool is on day 13 of SLAM. The water and vinyl liner are SOOOO clean! I'm so exhausted! We backwash....could there be something in the sand? I'm nervous about the safety of opening my Pentair up.

This is your primary issue. You need to test and replace more often. If you can't during work, then do it every hour when you are home and awake.

Post a pic of the light. DO NOT remove all the screws around the light. There should one screw in the chrome near the lens at 12 o'clock if your light is removable.

You sand is fine.

it is very sunny and very hot and so my shock level of 12 every hour is dropping below 12…so I assume I just keep adding chlorine each hour according to tests even though it’s getting eaten like crazy by the sun?

Moved from here.

With zero (or low CYA) - yes, sunlight is destroying the chlorine.
You want CYA at ~30 to properly SLAM.
