Ph or Alkalinity...which should i fix first

[JKashJ]

We've just started working on our water quality last Saturday and we shocked the you know what out of it for a week. The FC is off the chart, but the pool went from a murky green pond to a deep, cloudy blue. I've got an Aquarite salt generator and i had to add close to 400 lbs of salt to bring it up to 3400.

So, Alk and Ph are way off...both are very low. According to the calculator, with my pool holding 36500 gallons, I need to add 29.2 oz of Sodium Carbonate(soda ash?)..edit...read a bit more and can this be Borax instead? to bring the Ph up .2. So if i'm at 6.8 and i want to get to 7.4, i'll need to add approx. 87oz of this to get it up that level.

My Alk is 0 and it looks like i need to get up to 80ppm. According to the calc, i need to add almost 40lbs of Sodium Bicarbonate(baking soda?) to get this up to 80ppm.

So, does this sound right and which is most important to fix first. Also, it seems like i remember reading that alkilinity can be kept lower with SWGs.

Any suggestions on this would be great.

Thanks,

Kash
