5/30/20 0000 hrs:
Free Chlorine = 18.4 FC
Combined Chlorine = 0.4
pH = 7.6
Alkalinity = 90
Calcium Carbonate = 40
Cyanuric Acid = 100

I know my chlorine levels are outta this world. I’ve since turned my salt cell generator off. Any other recommendations? Thank you in advance.
 
Try this today just to be sure.

CYA Testing:
Proper lighting is critical for the CYA test, so you want to test for CYA outside on a bright sunny day. Taylor recommends standing outside with your back to the sun and the view tube in the shade of your body. Use the mixing bottle to combine/gently mix the required amounts of pool water and R-0013 reagent, let sit for 30 seconds, then gently mix again. Then, while holding the skinny tube with the black dot at waist level, begin squirting the mixed solution into the skinny tube. Watch the black dot until it completely disappears. If it helps, pour a little, look away, then look back and pour some more. Once it disappears, record the CYA reading. After the first test, you can pour the mixed solution from the skinny view tube back to the mixing bottle, shake, and do the same test a second, third, or fourth time to instill consistency in your technique, become more comfortable with the testing, and validate the CYA reading. If you are still questioning your own results, have a friend or two do the same test 2-3 times. Share your results only after everyone is done to see if you came up with the same average results.

If you suspect the CYA is still at 100 or more, let us know.
 
Well, no one here trust the store readings, but I have no doubt your CYA is too high and a water exchange will be necessary to lower the CYA. As for the Alk Up, they probably sold you a box or bucket for something like $14+ dollars when a 4 lb box of baking soda is the same thing for about $3.00. You have to cut that cord. The pool store will have you chasing your tail.

I am returning everything she bought. What would you recommend be my immediate course of action next?

With your Taylor K-2006C, do one more CYA test using the quote above in Post #4. If under good sunshine at your back the CYA is still at 100 or more, you'll need to exchange some water to lower the CYA. No sense adding chemicals that will only get pushed out onto the grass. Since you have a salt pool, getting the CYA in the 70-80 range would be ideal. Once the CYA is adjusted, then we can help you balance everything else properly.
 
If your 2nd cya test still reads 100 or more, perform a diluted test. The cya test only goes to 100 so, anything above that is just a guess. By doing a diluted test and doubling the result, hopefully it will drop under the 100 level on the scale. Then, you'll know how much you need to drain to get it near 70-80 for your SWG.

One other suggestion, use the 10ml sample size for the FC test. You will use much less reagents that way. 1 drop will count for .5 instead of .2. That is plenty accurate for our purposes. No difference between FC 7.5 and 7.2.

Ok, I administered another test. Also, I did (2) CYA diluted tests. Mixed 4 oz pool water (84 degree temp) & 4 oz luke-warm tap water. The following is my results. Note: My K-1106 Test Kit for Phos won’t be in ‘til beginning of week.

6/6/20 1630 hrs:
Free Chlorine = 5
Combined Chlorine = 0.5
Total Chlorine = 5.5
pH = 7.4
Base Demand (increase PH) = 2 drops
Alkalinity = 90
Calcium Hardness = 40
Cyanuric Acid = 100 (non-diluted)
CYA Dilution = 40x2 = 80, 45x2 = 90
Salt Level = 3,400

If the water is clear and no excessive FC loss, you can manage this without a drain. You will be adding some fresh water when you backflush and if you know you are getting a lot of rain, drain down a few inches before it rains.

Keep your FC in the target range for your CYA. You are at minimum right now, so make sure the SWCG is generating 3 ppm FC plus per day and test the TF daily.

Assuming I just take the average of my tests for CYA & call it 90, what would target free chlorine be?

Also, my salt cell is beginning to be near the end of its service life so I ordered a new Hayward T-Cell 9, I should have it installed mid-week, this week. I suppose I’ll put the Output % setting to 50 and go from there.
 
If you can cancel the T9 purchase, a T15 is more appropriate for your pool size.

See FC/CYA Levels for target range FC at that level CYA. Use the SWCG chart.
