Seachem Laboratories ASM051 Lil Mates Ammonia Alert - Fred Snapper

cute but i always have a problem with these coloring systems.where else in the world do you expect green to be warning and blue to be danger?oh, but yellow -- that's okay.i otherwise can't complain too much. it does what it says it's supposed to do, I think.this is in a 5gallon jellyfish tank i have set up.

They do not work at all, complete waste of money. I used them in my tank and despite knowing that the levels were high it always marked normal. So it threw that one out and used another one thinking it was maybe the one, but no they were both the same. Look for something else, this does NOT work.

This devise fooled me and my fish died.
