Review on Fish Water Quality API Test Kit by Samantha Salazar

I've seen many reviews that say the kit is defective because the liquid dyes in the bottle were green and orange so must have leaked or expired. I thought so too at first, but had to watch a few videos and found the following: With GH- the drops come out green. In water, it immediately turns orange. Once you've added enough drops, it will turn green again so you can check the levels. If yours immediately turns orange (it turns dull, see it against a white background) then it is much more likely that you have very soft water and not a defective product. Same with KH - the drops will turn yellow/orange, the water will first turn blue and then yellow again once enough drops are added. If you don't turn blue at all, you probably have very low CH (like me). If you have problems with your aquarium water, test your tap water. You will most likely see different results.
