sorry not much help here but i have always been led to believe that distilled water will have a ph of 7, the water that comes from my de-humidifier is always a ph of 7, so have to ask what your source is for distilled water as you may be getting something else.. sorry cant be more help, but if you goodle distilled water ph you will find more or less everyone is saying its a ph of 7, just thought i would let ya know.
Alrighty...the answer is: rhizotonic + airstone in hydro tank = rising pH. Got this from a very good thread over at icmag forums. I don't want to take the rhizo out, and I can't use H2O2....is it worth taking the airstone out? Or just sod it and change the levels twice a day??
i became a bit obsessed with water quality......
the problem with using "distilled" water is that the pH is always too alkaline......now, if you add your nutrient solution, it could bring the pH into a more acceptable range, but you must be sure to test your pH after adding your nutrients......for young seedling, i prefer to buy a jug of "Spring Water".....usually this pH isn't quite as high as "Distilled Water," but you could try a mixture of Spring and Distilled (or Spring and R/O water).....
The thing you've heard about leaving the water out for 24 hours is to help eliminate the chlorine in the water.....this proces has no effect on dissolved salts, organic contaminants, or microbial pathogens....
Adding an airstone will immediately "kick out" all of the CO2 molecules due to an interaction with the incoming Oxygen molecules......the chemical reaction explaining this phenomenon is unbelievably complex, but i have proof of it (a pond ecology journal)......lots of people get upset when their pH suddenly rises after they add an airstone because they don't understand exactly what is going on....
