Things You'll Need
- Peat moss
- Nylon
- pH test kit
Instructions
Boil water in a kettle and pour it over your peat moss. Allow it to sit overnight. This will encourage the peat moss to soak up as much water as possible. If you desire, you can add the water to the aquarium to help soften the water.
Fill a nylon bag or cheesecloth full of peat moss and hang it in your aquarium. It will start softening the water right away.
Test the pH of your water. If it is at a desired level, leave the peat moss bag in. Check your pH regularly to ensure the peat is still working. If the water starts to harden, replace the bag with a new one. If the pH isn't soft enough, you can add more peat moss to the bag.
