WyldFya;727909; said:How were you using them? Salifert and LaMotte are many times more consistent, and much easier to use. Seachems are more consistent then the API, which I have actually tried a several tests at the same time, and found that they are inaccurate. Only a few tests actually were testing the same readings, and that was with 4 master test kits, and 4 of the same test never lined up all together.
