1) Borax raises pH. It will raise Total Alk because raising pH raises T/A, but will not raise it additionally.

2) Baking Soda raises Total Alk. It will raise pH some, but don't plan on using it as your pH raiser. Arm and Hammer sells it in the familiar ORANGE box, and it's Sodium BI-carbonate.

3) Washing Soda is Soda Ash. Pool stores call it things like "pH UP!" but it's all the same stuff, Sodium Carbonate (not BI-carbonate!). Soda ash raises BOTH pH and Total Alk, the latter almost as much as Baking Soda, so you should NOT use Soda Ash when your Total Alk is good or high.
Arm and Hammer makes Washing Soda and sells it in a YELLOW box.

I don't tend to calculate amounts. If my pH is low, I add one pound of Borax, wait a few hours and retest. If it's still low, I add again until it's good.

I do the same with Total Alk.

If both are low, I'll add a pound of Washing Soda (not paying pool store rip-off prices!).

Add in small amounts, wait, then re-test.

The other day I had a guy in a pool store try to convince me that the Biogard alk raiser wasn't baking soda..."It's similar" and then used one of the alternate names the pool chem industry uses to fool and gouge people--Sodium Hydrogen Carbonate. I told him "It's not similar, it's exactly the same thing. That's an alternate name for Sodium Bicarbonate" Naturally he didn't want to believe me.
