I know the ph of 100% pure water is 7 and exposure to the air is supposed to bring down the ph a bit. why is my store bought distilled water ph 8.2?
First - exposure to air will not bring the ph of your water down. Maybe you are thinking about chlorine evap from tap water?I know the ph of 100% pure water is 7 and exposure to the air is supposed to bring down the ph a bit. why is my store bought distilled water ph 8.2?
Hmm. Well I would think the main benefit to distilled would be the low TDS. Our tap water is 160 TDS - which is acceptable. Of course I still have to use the ph down as the ph out of our tap is over 9+ (yikes). Do you know what the TDS is out of your tap? Maybe you are spending money needlessly?no im not thinking tap water, this is just what google tells me lol
I do have ph down but i honestly hate using the stuff especially if there is an option to buy water with a ph between 6.5 - 7 i hate using it because i have to always mix it the day of watering and you should wait at least an hour after you add it to check the ph for better accuracy. Im starting to doubt my milwaukee ph tester but i did just calibrate it earlier today.
I may just have to get some RO but i have heard distilled water is best.
