    Started using citric acid, 3oz per gallon . initial ph was around 1.5, but once skin added jumped to 2 ph by the end of the day. added probably another 6 oz of citric but didnt do much . So I have 6 gal and 24 oz of citric. Added 1.5 oz of safety just to get it down and it is stable at 1.5 now . With safety I usually run around 1floz to 1 gal of water and never have to add and stays at 1.5.
    Does citric run a tad higher around 2 ? is that safe pickle ph? would like to switch to citric going further for safety reasons and natural degreaser to aid in the pickle . But just concerned with the ph and is citric susceptible to ph movement more then safety.

    I use 3 oz per gallon and never check the pH.

    Any pickle should run from 2.5 to lower. Adding the capes to your mix will naturally raise the pH . I make adjustments the next morning or before I close up my shop. Citric can stay at 1.5 when it stabilizes with your skins. This happens with all pickles !

    X2 What Frank said! They all move around whatever you use. That's why you should monitor daily. Even your water can be different than the next guy.

    I always seem the need to adjust the pH the next day. So I keep checking the first few days. After that it's pretty stable.

    Sounds good thanks for the replies, With citric do you run seperate degreaser in your pickles aswell with deer capes? Or is citric enough with natural degreaser that it is sufficient ?

    I can't get my ph lower than 2.7 using citric acid and putting in more doesn't seem to lower it. I've already used another 8oz more in my 2 gallon mixture, compared to the standard recipe 3oz citric acid per gallon H20 + 1 pound of salt recipe and I can't seem to get it lower. I am using a ph meter calibrated to 7 using a ph7 solution so it should be accurate. Our water is 5.5. I don't have any other acid around besides vinegar. Will this work? Any advise is appreciated.

    I just tested distilled white vinegar and the ph meter read 4. So maybe my meter is off, since straight white vinegar should be somewhere around 2.5. I guess I will see the end result in a few days. Maybe I'll go and pick up some ph test strips in the meantime.

    what are you pickling in 2 gallons? Even with squirrel size critters I mix up 5 gallons.

    I still do a separate degreasing as that’s not enough to get especially bears degreased.

    Indeed the meter is off . I rather strips any day over a meter. Jmc
