The SWG will raise your pH and so will high FC. It is bleaching out the TA test. I would go ahead and try to lower the pH and see if that improves the appearance of the water. Is the SWG still running? What is the water temperature?

I am not sure what the temp. My thermometer stopped working Tues. Ill get a new one tomorrow, but I think it's probably around 68. It definitely warmed up today as it had 14 hours of sun.

Yes - I have it set to 40%. I was trying to stretch my liquid chlorine until I could get some tomorrw. It's going to be 85 and sunny tomorrow, so I was worried about running out.

Use Muriatic Acid. Don't try to lower it all the way down in one shot. PH is probably higher than 8, but use that as your starting point in PoolMath and add enough to drop it to 7.5 circulate for 30 minutes then test the pH again. Keep targeting 7.5 for the end result until pH is in the 7s.

This pool is going to make me crazy! I had the SWG set to 40% lastnight. I had been losing a lot of FC over night and assumed it would continue. Tested this morning and it was at 30. I turned the SWG off b/c I knew I would have enough liquid chlorine to get through the day. My FC is at 26 - it still hasn't dropped back down to 24 and I haven't added any today. Water is still a bit hazy, but much better than yesterday. I opt'd to hold off on the phdown since the appearance is better today. I'd like to get the chlorine right and then adjust all of my levels.

My pool is crystal clear today!!! It rained all day, so I couldn't get a picture of it. I'll do the oclt tonight!

Wouldn't you know, I get the pool clear and now my salt generator is giving me a temp error. Temp is 70, so not sure what's going on with it. It's a blue torrent swg.

Great 👍🏻 if you have passed all 3 end of SLAM Process criteria you can let your fc drift down to target for your cya FC/CYA Chart
Never let it go below target again. I keep mine on the high side so i know i have some room.
If you’re swg isn’t functioning just use the chlorine version of the chart for target.
When u get the swg sorted out You may want to get your cya to 70 to help your swg keep up in the summer heat.
