1. What brand test kits are you using for Alkalinity, Calcium and Magnesium in 2021?
Dkh-Hanna &/or Salifert
Ca-API
Mg-RedSea
2. Why are you using the test kits that you are using?
Dkh- I like the accuracy of Hanna, and I use the Salifert because both are fast and easy but sometimes I just want a quick ballpark check to vs ppm accuracy.
Ca- My calcium is repeatably good as long as my Dkh stays stable. API is fast and easy to use, and cheap.
Mg- I got this test a long time ago and I just purchase a refill reagent to make sure the levels don't swing too low as the corals sequester salts.
