I got lucky and got a Hanna alk checker on here and I have a standard salt water test kit. Other than those I've been testing once a week at the LFS's. What Cal and Mg kits do y'all recommend? What kits are more easy to do?
I've been using Salifert test kits, Mag, Cal and Alk for 10yrs, I have tried 2 or 3 others but these work the best for me. You need good light and go slow the last few drops.
