Review on 🐠 Alkaline Drinking Monitor for Aquariums - Ensuring Accuracy by Jeff Davidson

Testing the most valuable product for the effectiveness of PH tests for hydroponic gardening. Attempted litmus strips are a waste of time in my opinion. I love that they have 4 colored blocks to match with your next read. I wish I could consider testing them with my calibration solutions. I didn't do this as this is my first time trying to calibrate the PH controller and it was more than disappointing the first time, the strips are amazing but I think it's too expensive if you measure the PH set for several different plants. Requires at least two per plant assuming each requires a different PH than I require.
