Review on 🔍 Seachem Ammonia Alert 1 Year Monitor (3 Pack): Reliable Water Quality Monitoring Solution by Sandy Johnson

Easy to use, made of clear plastic, remove and place in the water tank. One of my tanks showed an instant color change. This enabled me to act immediately. I have also found that it is now making a splash in my aquariums. Any movement of the gravel right after this will cause spatter, so now I'm countering it with an ammonia wash. I ordered another one for my fourth tank.
