Before I started using the Guardian Monitor, I used to check my pH and temperature by hand and I would see the pH jump around and I wasn’t totally sure if the readings were accurate or if my system was in trouble.
pH is so important for both the fish and the plants that now I just look up and record my values once a day (or twice if I’m problem solving). The Guardian Monitor is fast and accurate, no messing around with test tubes and color charts.
Also, in the beginning I didn’t think EC was so important because the values were always low, now I’ve raised my EC my plants just rocket away so I know they’ve got the nutrient levels required.
I also use a Bluelab pH pen and EC pen to spot check all around my system to see if I’ve got any variation which could lead to trouble spots especially at the media beds.
They’re fast to use and accurate. I know my garden couldn’t run smoothly without the information these meters give me.
