The instructions ask for GH not DH. Whisch is why you need to dillute the test water, other wise the GH would be off the scale. Sounds interesting anyway.
It does work, I've used this method a few times. It might not be quite as accurate as a dedicated mg test, but it will certainly let you know if you are in the ballpark or need some correction.
