shrimpfreak Posted January 30, 2016 Report Share Posted January 30, 2016 I am using the API test kit and I had no idea what my PH was. I have Ada aqua soil that is about a year and a half old. I didn't know if my PH was high or low so I did both tests. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
