Review on 200 Aquarium Test Strips Accuracy by Jenna Hicks

Do not buy. It's garbage. If you have it, throw it away. I throw away all 3 bottles. It's cheap when I bought it I thought the lower cost must be because it only checks 4 parameters while most other brands have at least 7. And most of the time I'm only interested in nitrates, nitrites and pH. BUT no, it's cheap because the quality sucks. The strip gives totally misleading results for nitrate, nitrite and pH levels, too low compared to two other better brand name strips. I also confirmed this using a solution-based API test kit. Also, the color spreads terribly, making it almost impossible to tell what color it is. I've used at least 4 other different brands, none of them bleed. This product shouldn't even be on the market.
