You don't need any of the things they said! You do need a good test kit and need to do your own testing!
Bring your pH down to about 7.4 first! This will lower your alk reading since they move together.
Get your CYA up to 60-80 ppm second!
Your Alk and Cal are fine for right now....retest the alk once the pH is in range.
Once you get the CYA in range you will probably need to ajust the output on your SWG. maintain a FC in the 3-5 ppm range and you will have no problems.
If the CC goes above .5 ppm then shock with bleach. I suspect the CC reading you are seeing is because your CYA is really low for a SWG system.

If you want to raise your hardness then see if you can find DowFlake de- icer.
It is calcium chloride flake, exactly the same as hardness increaser, and on the Dow Chemical website it is one of the two products that they say is for pool and spa use!

I wouldn't worry too much about it right now since your ALK is on the high side but if it does drop much lower then you might want to bump it up.

I have the Taylor test kit, it always says I have a pH around 7.3 - 7.5 but when I take it to the store, the stores readings are always about .4 higher than my readings and my Cl readings are always 1-1.5 points lower than theirs, then again, i am looking at shades of pink and yellow, how accurate can that be vs. a computer. Should I shock with bleach or with the SWG?

I live in canada so my swg is only active 5 months of the year. or should I shock bleach it instead.

The general consensus here is to shock with bleach as it will save unnecessary wear and tear on your cell.

How do I know how much bleach to use to get rid of .2 CC?? based on a 15,000 gal pool.

Take a look at your SWG specs. Salt - 2900 ppm may be a little on the low side. The system will generate more chlorine at a lower setting with higher salt levels.

I have an Pentair IG20, the light indicates that it is still in the good salt range, I think its 2500-4000, I guess I could bump it up a little.
