So, I like to use the API Alkalinity test kit because it just uses the one dropper, but I miss out on the accuracy of the Hanna Checker or other multi-step test kits. The API test is 5ml tank water and each drop of the reagent is +1dkh until color changes. So I thought, what if I just double the volume, wouldn't that improve the accuracy? With 10ml tank water, wouldn't each drop be +0.5dkh until color change. Is my reasoning sound or would this not work like I expect?
