need a little help with advanced nutrients ph down pure concentrate. just wondering how much should be used to get a .5 ph drop in 5 gallons. i tried adjusting it last night with 30ml in 25 gallons and it shot it way way down. no harm done im i dont have my plants yet, i was just trying to stabilize my reservoir before i get my clones. right now ive got a shit ton of buckets aerating the chlorine out, and am planning on working this until i have it figured out but some help would be great.
a second thing, the people at htg supply (local store) told me to use pro-tekt to ph up, which i could probably just use tap water anyways, but it was a supplement i figured i would have on hand anyways, any help in that area as far as measurements go would be cool as well.
i'm pretty pleased with htg right now, i was down there last night (they just opened here about a month ago) and they gave me a free shirt. haha probably cause i told em i drove 30 mins to deal with them and had their lighter in my pocket. that and i told em i drove passed my homeboy's family's hydro store to deal with them lol.

i was wondering if anyone also may have had some info on how the perfect ph buffer products, i think AN makes one, and if so does it work well? i'm trying to make this as low maintenance or as easy as possible, because sometimes i will have to be on the road for a week at a time and my girlfriend will be maintaining the grow. i plan on premixing 5 gallon buckets of what she can reup the res with to make it easy on her.
