problems with chemicals on startup

[Idigress]

We put up and filled our Intex AGP (8400gal) Thursday evening. Added 210lbs salt, ran sand filter pump for 16 hours, then switched on saltwater system, ran that for 8 hours. Here are my readings:


[FONT=.SF UI Text][FONT=.SFUIText-Bold]Free Chlorine (FC) 0[/FONT][/FONT]
[FONT=.SF UI Text][FONT=.SFUIText-Bold]Combined Chlorine (CC) 0[/FONT][/FONT]
[FONT=.SF UI Text][FONT=.SFUIText-Bold]Total Chlorine (TC) 0[/FONT][/FONT]
[FONT=.SF UI Text][FONT=.SFUIText-Bold]Copper Ions (weekly) 0[/FONT][/FONT]
[FONT=.SF UI Text][FONT=.SFUIText-Bold]Cyanuric Acid (CYA) 0[/FONT][/FONT]
[FONT=.SF UI Text][FONT=.SFUIText-Bold]Acidity/Alkilinity (pH) 7.8[/FONT][/FONT]
[FONT=.SF UI Text][FONT=.SFUIText-Bold]Total Alkalinity (TA) 240[/FONT][/FONT]
[FONT=.SF UI Text][FONT=.SFUIText-Bold]Calcium Hardness (CH) 600[/FONT][/FONT]
[FONT=.SF UI Text][FONT=.SFUIText-Bold]Total Hardness (TH) 800[/FONT][/FONT]
[FONT=.SF UI Text][FONT=.SFUIText-Bold]Salt (weekly) 1500


I checked the electrolytic cell and it was loaded with scale. So I've got everything turned off and the cell soaking in vinegar. What chemistry do I address first?

Thanks ?

210lbs of salt in 8400 gallons should have added almost 3000ppm of salt. Which test kits are you using for these results?

You should first establish a FC level using bleach, then turn on the SWG to maintain that level.

Does salt loose its effectiveness after 2 years in the garage? Also, test kits are old. I think that may be my biggest problem. Off to get new testing supplies!
