How to Clean Rocks from a Fish Tank

Are the rocks and decor in your freshwater aquarium looking a little dingy? If so, all they need is a good cleaning, which can be done with ease.

Things You'll Need

• Large pot Stove Large strong tongs Large bucket Bleach Dechlorinator

Instructions

1. Remove rocks from the aquarium and put them into the pot.

2. Fill the pot with water and boil the rocks for at least twenty minutes. This kills bacteria and removes anything that might be clinging to them.

3. Remove the rocks from the pot with tongs and place them into a bucket.

4. Fill the bucket with water and one cap full of bleach per gallon of water.

5. Let the rocks bleach overnight.

6. Dump bleach water from the bucket into a safe area.

7. Refill the bucket (with rocks in it) with water and add dechlorinator, according to the manufacturer's instructions.

8. Let the rocks and water dechlorinate overnight to be sure that all the bleach has been neutralized.

9. Return the rocks to your aquarium.

Tips & Warnings

• This is for freshwater tanks only. Do not bleach saltwater aquarium rocks.

• Wear old clothes when working with bleach to avoid ruining good items.
