I had a sub pump running in my rez just to keep nutes mixed up, but I wanted to take it out cuz it would heat my rez alittle everyday. Im replacing it with a big air stone. My problem is when I unplugged it and took the pump out of the water it automatically dropped the ph to 3.8 from 5.9 which never would move otherwise. What he fuck is up with that?!?! It can't be an accurate reading can it? I've never had a problem with my meter before. My plants have fed 3 times today with it like that and they look fine. . . .
