Review on 🌡️ Seachem pH Alert Test Kit for Freshwater by Diana Scott

I have a ph sticker and an ammonia sticker. Both do not change color. My wife sells hobby fish, roosters, roosters, etc. We have 30 tanks and have used them in tanks that we know from water testing have poor pH and ammonia and none of them have changed at all. Stay away from those in my opinion. not only because they don't work, but also because you can make them think everything is fine in the aquarium while your fish are suffering and you think everything is fine.
