I couldn’t agree moreSalifert.
Hanna for alk, salifert for calcium and magnesium.Looking for the best test kits for lowest price I’m looking at getting into the hobby and lost all my old test kids and wanting to go cheap
Why do you say the Hanna Checker is more accurate than the Red Sea Pro Test?I prefer red sea for calcium and magnesium. The procedure is a little easier to be consistent and the overall cost per test is better (initial cost is a lot higher cause it's 100 tests. Refills are very cheap). The alk is nice too, but a little less accurate than the Hanna.
Red sea accuracy is not 0.15 that is the precision per ml of titrant used. A single drop of the titration is about 3ml and its hard to accurately tell the end point. In the real world, your titration will vary 5-6 ml between tests of the exact same water sample. This is almost a 1dKH variation. The Hanna is much more consistent between readings like within 0.1 dKH usually, sometimes 0.2Why do you say the Hanna Checker is more accurate than the Red Sea Pro Test?
By their own specifications, the Red sea accuracy is +/- 0.15 dkh whilst the Hanna is +/- 0.4 dkH.
The Salifert is +/- 0.3dkH
