Hanna Calcium Checker
Posted: 9/8/2016 from BOCA RATON, FL UNITED STATES
This checker is fantastic. It looked a little overwhelming at first but there great videos online. No more checking colors on chart, no more counting drops of solution and then referring to a card. We were using another tester and calcium read normal but our corals weren't doing well. The Hanna Calcium Checker showed that the Calcium was way too high. After a week or so, corals look great. They are opening big, colorful and look much healthier.
