ELOS KH test clarification

[Nonfamous]

Okay, so I'm using an ELOS test kit for checking my KH. The instructions say add a drop until the colour turns from Cyan to Yellow. I'm having a difficult time with doing this.

First, the water never really turns Cyan. It *might* have a slight blue tint to it after a drop or two, but its hard to say it Cyan. After adding 10 drops (KH of 5) the color turns to orange, not yellow. I tried to add more to see if it would turn yellow but it never did.

What am I missing here or do their colours simply not match mine? When the colour changes to orange, should I take that as yellow?

Since I go zero clarification......

I tested last night....again.... this time with the test tube on a sheet of white paper. After 2 drops is was noticeably blue. At 16 drops they was a slight indication that it turned yellow. Not terribly distinct, but noticeable. I do not recommend this test. I'm sure there are better ones out there.

I have never used that test kit before. I'm guessing no one responded because no one else has either.

When it comes to testing KH ( alkalinity ). I prefer the little cheap API kit.Mainly because it's easier for me to see the colors while doing the test.
