I have well water, what challenges can I expect?
How does reverse osmosis affect pH?
Another reason to question the pH reading is that for any water sample which is very low in TDS it is very hard to obtain an accurate pH value. The worst case of this accuracy problem occurs with de-ionized water but some low TDS RO water will react the same. The sample is so low in minerals that there is no buffer. The slightest absorption or loss of CO2 shifts the pH substantially. The water’s tendency to pick up additional CO2 from the ambient air, even if the test is done on site, can produce a very low false pH.
In reality, measuring the pH of RO water is difficult and not accurate due to lack of any pH buffering the RO water. If the feed water has a lot of dissolved CO2 then pH can drop a few points. But, in the case of a drinking water RO system, a post re-mineralization filter will help neutralize the final product water's pH level. In the case of RO water for horticultural purposes, once you mix a calcium/magnesium supplement into the RO water and then add your nutrients and additives, the final pH can be adjusted and your feed formula should be pH stable.
Why do pH levels come out higher than the source water when running water through a carbon or Carbon/KDF filter?
