Soda ash (borax) brings it up and lemon juice brings it down.

Thank you, but has anyone tried that in conjunction with food grade H202? Do you know people who use this system?

using hydrogen peroxide is nothing new to the spa industry, it's been around quite some time as an alternative to chlorine/bromine so your 'traditional' ph adjusters (Sodium Bicarbonate aka Baking Soda) will increase ph/Alkalinity and Sodium Bisulfate aka dry acid will lower ph/Alkalinity. Calcium Hardness can be increased with liquid calcium but only lowered by using a softer water source to fill the spa...Good Luck!

Thanks! I think I am getting the gist of it. I had an issue of having too high of a PH (8.something), and too low of TA (well below 80ppm). I went ahead and tried to decrease the PH with Apple cider vinegar (you don't need very much, 1/2 cup did it for me, and there was no vinegar smell at all). Then I used only 2 tablespoons of Baking Soda. Both came to the middle with the TA raising to around 100ppm and the PH decreasing to a normal 7.8-ish. Even if we have to adjust this every 2-3 days or so (we'll see how it goes), I still find that very cost effective to a harsh chemical system. I am stoked! :) ;D

Just keep in mind Alkalinity and pH buffer off of each other so your goal is to 'mess around with' <----very scientific term...your Alkalinity until your pH stabilizes so you don't have to adjust it every few days, some people need to run their Alkalinity around 40-50ppm to 'lock' their pH level in where some it may be 80-120 ppm, every water source is a little different of course. Just keep some baking soda and acid (vinegar, sodium bisulfate from a pool/spa dealer, etc) on hand along with your weekly dose of hydrogen peroxide and you should be fine!

Thank you again.. I will keep this in mind.
I'll try to update every now and then to let others know how its working out.
Lastly, out of curiosity, do you (or anyone else for that matter) know anything about adding silver or copper? Can these be combined with H202 safely, and if so, how do they effect PH/TA levels?
