Review on Seachem Ammonia Alert 1 Year Monitor by Laboratories by Josh Akin

Received and fitted 13 days ago, is the color still as gray as when it was delivered? Change the saltwater in my 400 gallon tank weekly and use a commercial water conditioner on my tarpon crabs. Does the color stay the same on the meter? Have you used rapid test strips and the sensor seems defective? I'm waiting for the seller's response and will update the rating! 👍
