Where are the instructions? Under the label!
But I’ll save you some trouble, use 2.5ml per gallon. What!? metric and standard together! That’s half a teaspoon per gallon for you yanks! Oh, and I know you are wondering this too- treats over 20 gallons. I see another review that says they add this to a gallon of water they have on standby, but I’m not sure that is a correct use as there isn’t anything in new water for the bacteria to consume and they will die and not be useful when added to the aquarium. Also cannot recommend to use this to eliminate chlorine as the manufacturer (Fluval) doesn’t state it does that!

Aquarium water treatment

Made Tank Way Worse Overnight
This stuff did quite the opposite in helping to dissolve waste matter in my 3.5 gallon betta tank. I had to do a complete water change after using it as I had added it to the tank the night before and by the next day the tank water had very visible cloudiness that could not have been good. I could not return it so I threw it away. I saw no improvement but only a bigger concern with the water quality after using this.

Now I am rushing to buy my toddler a replacement fish
Killed my toddler’s fish in less than 6 hours. No directions on the bottle (had to google even how to use it) and apparently that was wrong information. Now we are rushing to buy a replacement fish, and soaking his tank to get this poison out of it.

Killed my fish
I have had my fish for a few months now, I cleaned the water just how I always would and I put the water purifier in the water and my fish started swimming to the top and put its mouth above the water (which is an indication that something in the water isnât good of quality). I donât recommend buying this product unless you want to kill your fish.

Killed my fish in 3 hours. Sad.
Used half the recommended amount. Turned the water a bit cloudy right away. My little betta went from happy and active to dead in 3 hours. How can you sell this product? The reviews of this product are highly suspicious.

After adding this to the tank, my Beta fish smiled and proceeded to build and play a Ukelele. It was amazing.
