I'd like to buy a monitor that will tell me ph/tds/ec/temp of my res. I see one called Bluelab Guardian Monitor pH/EC/TDS/Temp. I watched a youtube vid of the guy saying it didn't work well. My hanna pens keep dying so I'm over hanna and I'm over pens my back can't take the pain anymore, I know hanna makes a tri meter but I'm not interested with my past experiences with they're products. Does anyone have any suggestions for a good product for me? Thanks. ![Joint :joint: :joint:](/styles/smilies/joint.gif)
