Ph problems

[Kristin]

I just opened our above ground 18 round pool. I tested the ph and it's a very light slightly orange color. I use the 6 test tester that you'd buy at places like Walmart and it doesn't even show colors that light. What would I add? Baking soda or borax to bring it up? Any ideas how much?

Thank you!

Use borax to bring it up to range.
