C02 drop checker starting color yellow

[Patrice]

I have greenish yellow color instead of blue.

Using co2 drop checker from eBay(the one with multiple color.) I did all i could do, i have a perfect 4kh by doing multiple test. Added 90ml of distilled water to 40kh of distilled water.

I don't understand. i did it 4 time. still the same result.Im going to have a meltdown.

The drop checker solution that comes with the Chinese drop checkers is crap. Don't use it. Use your own low range pH test, 2-4 drops.
