Do test kits Expire?

[dogmaiwli]

IE, ammonia, chlorine, chloramine, ph, nitrite kh gh etc. etc. etc.....
do they expire and if so how long, is it different for each kit????

Eventually yes they will. Just to be safe though i replace them every year or so...

I found (and assume) that test kits that have an experation date on them expire, and well, ones that dont have an experation date dont expire.
