i have well water that ranges from6.8 to 8.0 and i have 30 gal res and i only need to put 15ml of ph down per 30 gal res to bring down to 5.5 so would it not be easier to just ph down the water instead of spinning ur wheels like ur doing going here and there and mixing ur self all up when all u had to do is not buy weed for a day and go buy the damn ph meter and a bottle of ph down??and btw after i add the 15ml of down buy using the big res i don't have to add anymore like u do with a 5 gal bucket or small res.

p.sI incorrectly assumed that the pH of tap water would be somewhere around 6-7 and letting it sit would evaporate the chlorine, thus leaving usable water with a moderate pH level. Everywhere I read simply said if using tap water, to let it age for 2 or 3 days before giving it to the plants. This was only an assumption I had made that turned out to be false.

sorry but letting the water breath/evaporate is'nt false, as u say but rather true but it's ment to evaporate the chlorine not everything in the water/ie minerials.and i have watched everything u have, and i know this so to say it dos'nt have this info in the stuff u have seen and read is false. or u have a.d.d ,sorry but im not tryin to be mean but i've seen u post in this thread and others, as if it's 4 ur friend but yet everything we tell u seems to go in 1 ear and out the other???so i don't know what to say but u say in this day in age with sites like this and others and people on here to help u why buy a book...i don't know maybe to read it as u can never learn too much and in the faq on this site taought me most of this common stuff like ph and ppms and sex and well pretty much all that stuff i could see if u had a ? based on what u have read to fill in the blanks but u keep askin the same thing over and over and u keep gettin answers over and over so i don't know what to say....
