Pet's info: Fish | Tropical Fish | 5 days old

How often should I put Tetra dechlorinator into my 2.2 gallon fish tank with three guppies in it? I know the amount, I just need the best time in between please. Thank you!

You should only have to add dechlorinator when you add new water from the tap. Otherwise the treated water should not accumulate chlorine on its own. I hope this helps and please feel free to post any additional questions.
