well the first question is do you need to buffer your top off water?
i know it may seem stupid, but just need to check.
now, to my knowledge you can store it for some period, i would store it to long, but you can. i would make up a 5 gallon bucket of top off water, and adjust the
PH as needed. and use that. why thats used up do it again...
you should not have to worry about hard/soft water..
this term refers to the mineral (and stuff) content of the water. as long as you are using an
RO/DI unit 99.9% of this will be removed, so its not a real concern.
