The PH battle

[stinkyattic]

1/2 liter of PH down lasts about as long as a gal. of PH up for me. I also notice that it takes much more PH up to raise ph than it does PH down to lower it. .

Yeah and this is because pH up is (I believe) Potassium hydroxide, KOH, and pH down is Phosphoric acid, H3PO4- a tri-protic acid, and VERY strong.
The active components in each are the -OH group and the -H respectively.

Well NO, but no one should expect perfection so Ill give it another try. . . I have battled low PH from day 1. If I set it at 6.5, in 24 hours its under 6.0. Double check by using the meter and the drops it plunges. So I used the entire bottle of PH UP in just over 9 weeks and I opted 3 nights ago to use Baking Soda to raise the PH.
