Mail-In and ICP Aquarium Water Testing:
Which Service is Right for You?
Many hobbyists admit they do not test their aquarium water parameters often enough. The advent of mail-in water testing for home aquaria makes it easier than ever to record, track, and analyze what's going on inside your aquarium.
There are four major water testing labs specializing in saltwater analysis: ATI Lab, Aqua Medic AWT, ICP-Analysis.com (CoralVue), and Triton Lab. We wanted to see what it was like to go through the "ICP Experience" with each of these four testing services.
Identical water samples were taken and sent to all four testing labs. The goal was to look at variances within the results (which are expected), but more importantly compare the benefits of each service in order to help you make the best decision for your reef tank.
