Will stabilizer lower PH? The reason I ask is that I put in 3 lbs of stabilizer to raise my level 10 ppm. I also put in 1/2 gallon acid. Later on I read the test and the PH was around 6.8- light peach color. Previously it was 8.2. I didn't think 1/2 gallon acid would do that much to ph- btw 26,000 IG vinyl
