High pH and the Randy's two part system

[altunian]

My pH is a bit high (8.5), so I have to use the 2nd recept of Randy. But as I compare the first and the second one, I see, that they are actually the same, only the concentration of the second is exactly 50%, compared to the first, but the applied amount of the solutions is doubled - so where is the difference between Recept #1 and #2?

Thanks sincerely for any help.

Recipe 1 is baked baking soda so it has a pH raising effect. Recipe 2 is not baked, and has no pH raising effect. It is less concentrated because the unbaked baking soda is less soluble in fresh water.

thank you so much for your answer - I did'nt mention that difference! I will try that!

You're welcome.

Good luck. :)
