    False results

    By Suncouch on Dec 7, 2021

    Strips have a weird setup of pad and plastic cover- couldn't get it to test right- after dipping it in water would either remain yellow on inside, blue around the edges, just yellow, or if I squeezed it, would turn blue. Led to a false sense of security when in reality was the cause of fish dying!

    Works like it says

    By tricia on Feb 14, 2021

    Fairly easy and accurate. I have 2 tanks and they read differently, so it's not like they're duds.
