How to sterilize aquarium plants with hydrogen peroxide

To use hydrogen peroxide for aquarium plants, you need to create a solution with water and hydrogen peroxide. You do not want to use straight hydrogen peroxide, as too much can cause damage in some plants.

To create your solution, add one teaspoon of hydrogen peroxide to every gallon of water. To sanitize the plant, dip it entirely in the solution for 30 seconds.  If you are trying to get rid of parasites or algae, allow the plant to soak in the solution for five minutes before removing it.

After dipping or soaking your plants, rinse them off with water. If any algae remain, gently scrub them off, and then you can return your plants to the aquarium. Be sure you are using 3% hydrogen peroxide for the cleaning solution.

Other Alternatives For How To Disinfect Aquarium Plants

Though hydrogen peroxide is a great way to sanitize your live aquarium plants, there are other ways as well. Though you don’t want to use cleaners such as Windex or Lysol, there are some common household products that you can safely use. They will work to clean your plants and rid them of any ailments.

When used correctly, bleach, potassium permanganate, aquarium salt, and vinegar are all effective solutions for cleaning plants. They work to clean, disinfect and rid your live plants of parasites, snails, bacteria, and algae. It is important to keep your aquarium plants healthy so they can grow strong.

Bleach dip for aquarium plants

Though bleach can be harmful to plants, when used correctly it can work as a disinfectant. A bleach and water solution will work to clean your plants without harming them.

To make your bleach solution, add one cup of bleach to 19 cups of water. Allow your plants to soak in the bleach solution for two to five minutes. After soaking, rinse them off thoroughly with clean water.

Wipe off any excess algae that may still be on the plant. Then, allow it to soak in clean water for 10-15 minutes to ensure all the bleach is gone before returning it to your fish tank. Bleach can be harmful to fish, so don’t skip the second soak which is just clean water.

Potassium permanganate plant dip

Potassium permanganate is an effective disinfectant that can be used to disinfect plants. Be sure not to get it on your skin or clothes, as it will stain.

In addition, be sure not to combine potassium permanganate with solutions or medications that contain formaldehyde. The combination of the two will cause dangerous chemical reactions such as combustion and the formation of noxious gasses.

To use, fill a container with clean water and then add potassium permanganate. Add it until the water turns pink in color. Then, while wearing gloves, place your plants into the solution and let them soak for 10-15 minutes.

After soaking in the solution, rinse your plants thoroughly with clean water. Then, let them sit in a new bucket of clean water for 15 minutes to remove any leftover residue before returning them to your aquarium.

Aquarium salt for plants

Aquarium salt is another effective way to help your plants. It can be used to effectively rid your plants of snail eggs.

In addition, aquarium salt is also used to treat infections, wounds, and parasites in fish. You can also use it to lower nitrites in water, reduce stress and prevent algae.

To use, combine one cup of aquarium salt with one gallon of water. Let the plant soak for 15-30 seconds in the solution and be sure not to let the roots in the solution. Then, rinse off the plant and return it to your fish tank.

Vinegar plant dip

Vinegar is another common household product that you can use to clean your aquarium plants. It is a great way to remove built-up algae from your plants and even your aquarium decorations as well.

Combine one cup of vinegar with one gallon of water. You can use cooking vinegar with acidity between 5-9%. Place the plant in the vinegar solution and allow it to soak for five minutes. Then, rinse it off thoroughly with clean water before returning it to your fish tank.

Keeping Your Aquarium Plants Clean

Aquarium plants can easily become dirty with algae, bacteria, fungi, parasites, and even snails. This can be damaging not only to your plants but also to your fish as well. Fortunately, you can effectively clean your plants to keep them healthy and growing.
