The bacteria are only about 25% efficient when pH is around 6.5, and they go dormant at pH 6. I think you're doing fine, it's just slower thanks to the lower pH level. Eventually you'll have grown enough bacteria that they'll be able to convert the 2 ppm ammonia overnight to zero and nitrite also to zero in that time.

The Nitrate pad detects Nitrate in solution at 10, 25, 50, 100, 250, & 500ppm. The Nitrite pad detects Nitrite in solution at 1, 5, 10, & 25ppm. < lb nitrite × 1,000,000 = ppm green weight of meat block In comminuted products, this formula can be used to determine: (1) The permitted weight of the nitrite, if you know the weight of the meat block. (2) The minimum weight of the meat block that must be used in the formula, if you know the weight of the nitrite being used. Sodium nitrite shall not exceed 200 ppm ingoing or an equivalent amount of potassium nitrite (246 ppm ingoing) in dry cured bacon based on the actual or estimated skin-free green weight of the bacon belly.

2018-03-01 · The use of nitrite in meat products is only allowed in the form of sodium nitrite (NaNO 2). In this study, the nitrite salt used contained 0.6% of sodium nitrite blend with sodium chloride (NaCl). Therefore, 150 ppm of NaNO 2 is brought by 25 g/kg of nitrite curing salt.
