"Much like their pH test kit, this one uses a tube and test solution. Simply add 5ml of water into the tube, then use the two solutions, shake, and wait five minutes. Easy to do and accurate. The color chart is easy to read, too."
"This test is easy to do and easy to read. The colors are clear and distinct. There is enough of the solution to last for years of weekly testing, and it is inexpensive compared to other products that measure ammonia. I highly recommend it."
