Perfect, look no further

This is the only brand I have ever used in my 15 years of having fish tank. It's ease of use by filling a cap to 5gallons water. I let it set about 20 minutes, but it's always been ready to add instantly. I never drain water or have to syphon the tank. No need for cleaning because it's a natural self sufficient echo system.

Works as intended

I use Tetra AquaSafe Fish Tank Aquarium Water Conditioner in our outdoor koi %26 goldfish ponds when their water level gets too low and I have to add water. This product reduces the harmful chlorine, chloramines and heavy metals that would make my fish meet their demies.
