AND IT WAS ACCURATE! Compared the reading to my 2013 ammonia kit and it was within the same parameters so....do we really need to replace them every year or so??
Someone gave me a super old test kit with a craigslist tank I bought. I mean its at least 15 years old and it works fine. To each his own I guess, if you feel like you need a new test kit every year by all means get one, just send me your old one!
