Review on 🌊 Hanna Marine Alkalinity Checker HC - HI772: Accurate & Efficient dKH Measurement by Denise Portis

Just received it today and it's great. I hate trying to decipher when the color changes on normal tests. I've tried to keep the alkalinity at 9.0 but it's hard to tell if it's 9.0 or 9.8 [precisely in as broad a range as I thought I was] I'm pleased To be able to report that I checked right away and it was 9.0! Checked again to be sure. 9.0 again. I highly recommend this product
