Adding baking soda low tA

I am replacing everything. The reagents expired 2 months ago.
Those numbers from LPS are suspect.

Post a full set of results when you get fresh reagents.
Until then, use 40 as your CYA and dose to the high side of the FC range for your CYA.
FC/CYA Levels

If you run out of reagents again, just so state rather than post pool store numbers.
TFTestkits has a sale every March for refill kits. You should replace your reagents then.
How old are you other reagents?

Your other numbers look good.
Ok I retested my pool this morning. We fixed the o ring on the dome because the filter dome was leaking. I will be adding 3 gallons of conditioner tonight to raise the CYA as I have 30.
The display box shows I have 2900 in salt but my tests shows higher. Should I be concerned of the salt reading on the box as an issue with the salt cell? Advice ?
 
3 gallons of liquid conditioner is expensive.
Just get the granules and add using the sock method.

Reduce pH to about 7.5
Once TA gets to 60, run pH at 7.8-8.0

If the SWG is happy making chlorine, just leave the salt as is.
 
The box system is giving me the orange light and indicating low salt at 2700 when I have higher than that so I should call Hayward? Or?
