Query: Too hard to handle

This test purports high accuracy, and that may be so. The high sensitivity test (read after 30 minutes) is certainly very sensitive.The sensor disks are ridiculously clumsy to handle, though, and setting up the test with tweezers is a time consuming and frustrating process.You'll test more often with the dropper-bottle and test tube method. That is much more important to safeguarding your fish than knowing the ammonia level to the tenth part per million.I would not buy this again and will probably not use it once my new tank has cycled. Stick with the API Master Test Kit.
