I will probably try to do that today I've just never used one before and I got a high tech one so I'm overwhelmed. Any tips for calibration and taking the readings?
I would either go to your hydro store or ebay and pick up some calibration solution. I get the 7. Also you will want to either use that or some storage solution and pour a little into the cap of the ph pen. You dont want the probe to dry out. If the probe gets messed up your readings will be way off. I usually calibrate mine weekly if needed. Better to be overcautious then to be wrong haha
