So I decided to test my Po4 today. First test said 0.17 (i cried a little). Didn't think that was correct because everything is looking pretty good. With the exception of my sps because well they always dont look great.. lol Tested again. Second test said .05 (i was a bit more pleased..). I figured for good measure one more test.. 3rd test said 0.. Im stumped.. Any ideas? I just replaced the battery not to long ago..
