Anyone down the New London area have a reliable digital PH meter they trust? I'm having the worse time getting a good reading with an API test kit and I don't trust my PH probe on my RKL. Would like to get ahold of one for a day and use it to compare against my RKL and get a good gauge on where I'm currently at. Think I'm experiencing or experienced a drop but just having a hard time determining exactly where I am at this moment.
