You guys don't need all of that stuff. Brita water filters remove chlorine along with other contaminants and particulates AND fix PH. You can let high PH water sit out for the next year and it will still not fix itself so it will still need fixing before it should be used. Your best bet for PH is get yourself a cheap water test kit (under 10 bucks, I have pics here somewhere of it) as already mentioned and check your water regularly. Outdoors it's not so important but indoors it is critical for healthy plants and good yields.
