Club soda - done to death but read on

To note i realize not all carbonated water is created equal, but I picked up some Walmart Great Value club soda for my daughter she likes "fizzy water". Anyway I read the label and it has listed for ingredients as carbonated water, potassium bicarbonate and potassium citrate. Also lists that it's not a significant source of sodium.

I busted out the tdc/ppm meter and ph, clocks in at 116 ppm and ph of 4.83. This is much lower than my tap water at 280 ppm and ph of 7.2, primarily calcium and a few other elements.

I think this is a winner, can use to drop my ph of rainfall runoff as it sits at about 6.8 after it sits in house for a while absorbing carbon, so drop ph with club soda and add potassium esp in mid to late flower.

Anyone try this low sodium version?

I would think you'd need to use alot to bring down the PH on big batch of water.. how much water we talking ?

The ph will be low because of the co2 forming carboxylic acid. But it is temporary. As soon as the co2 dissipates, the ph will change.

Some well water has naturally higher levels of co2 (not bubbly, but there). The ph will be low for a day or two then rise if left out. Drives people with fish tanks nuts.

Ph was for flat soda, not sure yet how much to use, may be a 2l every two weeks?
