How to make your own chlorine neutraliser for your aquarium

Tap water contains chlorine or chloramine as a
disinfectant to control bacteria. Chlorine and chloramine in tap water is harmless to humans but is deadly to fish unless a chlorine neutraliser is added.
Making this chlorine neutraliser is easy and cheap to make and you don,t need much to make it.

Things you will need:

• sodium thiosulphate

• a measuring cup

• distilled water

• a teaspoon

1.  First you take your measuring and throw some sodium thiosulphate crystals in, the more crystals you throw in, the longer you,l wait until its dissolved.
2. Next you throw some distilled water in to, the water should be equal to the crystals otherwise the chlorine neutraliser will be ineffective.
3. Wait. It takes a long time before the chlorine neutraliser is finished and that time is about at least overnight.
4. That's it! it,l look like this when its finished. After you used the sodium thiosulphate, put in the refrigerator for later use otherwise the crystals will melt. About 3 drops is enough to treat 10 gallons (37 liters) of fresh water.
