OLDJIMMYBONES Reviewed by OLDJIMMYBONES on . pH Problems?!?!? My digital ph reader is showing 5.76, but when i tested with litmus paper its showing a deep red, very low, it there any chemicals that could mess the litmus papers reading up? using superthrive, liquid karma, & pure blend, any ideas? is the paper wrong or the digital?
