So, my pH was about 7.9 after a couple of days of running my system. I then tested my calcium and alk levels to make sure they were good. Cal was 420, and alk was 8. I usually run at 500 and 9-10 alk, so I went to brs (I use their 2 part) and added what was required (not a full dose for alk since it would raise it too quickly), and my pH dropped to 5.6!!! I'm still cycling, so there's no livestock, but wtf just happened? I mixed everything according to instructions, and since when does adding soda ash REDUCE pH????
