Help with pH please!
Hello, I seem to be having a problem and was hoping you could help me. Everytime I adjust my pH it seems to climb back up to the original waters pH, for example if the original water's pH was 7 and I dropped it down to 5.5 it will climb back up to 7 in a couple of hours, it seems no matter how much pH down I use it will always climb back up, and using this amount of pH down can't be healthy, right? The PPM out of my tapwater is only 50 and it's pH is 7, I need it to be 5.5. Do you have any idea of what I can do?
