Live aquarium plants make for a good addition to any fish tank, whether saltwater or freshwater. Plants look nice, they make your fish feel at home, and they do actually help clean the water a little bit too.
That being said, live aquarium plants do get dirty, covered in debris, and algae can build up on them too. In other words, you need to keep those plants clean.
How To Remove Algae From Aquarium Plants
Algae and other debris can affect plant health in a negative way, not to mention that it just doesn’t like nice either. How to clean live aquarium plants is what we are here to talk about today.
1. Rubbing The Plants Clean
One of the first and easiest ways to clean your live aquarium plants is by rubbing the algae and other debris off of them with your fingers. Make sure that you have washed your hands really well for this, ensuring that your rinse all soap off your hands thoroughly for before beginning.
This method is as simple as grabbing the leaves of the plants, and the stems, with your forefinger and thumb, gently rubbing them so that algae and debris comes off.
Make sure to use something like an aquarium vacuum or a fine net to catch all of the debris and algae that comes off of the plants. This might not be the best way to get plants clean if they are already excessively dirty, but it is a good way to maintain clean plants once they are actually clean.
2. Use A Toothbrush Or Algae Pad
If simply using your fingers to rub the plants clean inside of the aquarium is proving to not be enough, you will want to take it one step further. For this method, you will be using a soft toothbrush or an algae pad to remove algae and other debris from the live aquarium plants. This method is fairly easy, plus it does not involve any chemicals, something which we really like.
Start out by removing the plants you have selected for cleaning from the tank. You can place them in the bathtub or sink. Remember to not remove all of the plants at once as this can cause a lot of stress for your fish. While removing them, check the plants for snails and other creatures that may be hitching a ride. You want to leave those inside of the tank.
Use the toothbrush or folded algae pad to gently clean the algae and other debris off of the plants. Make sure to use a fresh algae pad or a toothbrush specially dedicated to this. Never use an old toothbrush that once had toothpaste on it.
Remember to be gentle here. Once you are satisfied that you have scrubbed the algae off, use some clean water to rinse them off before putting them back in the tank.
3. Using Bleach To Clean Aquarium Plants
If simply rubbing or brushing the algae is off is not doing the trick, you might have to take it one step further. Yes, sometimes algae and other dirt from aquariums can really stick to live aquarium plants.
For this method, using a bleach bath can help loosen any sticky particles. Even better is that bleach will effectively kill off algae and any bacteria that is on the plants.
Cleaning Aquarium Plants With Bleach
For this, you want to take around 4 tablespoons of bleach into 4 gallons of water, thus creating a 10% bleach solution. Any stronger than that and it may negatively affect your plants, but any weaker than 10% and it probably won’t do the trick. Don’t use any kind of gel bleach or scented bleach because those things are nearly impossible to wash off of live aquarium plants.
Simply soak the live aquarium plants in the bleach solution for about 5 minutes. Really thick and hardy plants can take 5 minutes of bleach soaking with ease, but more delicate plants can only handle 2, 3, or maybe 4 minutes. Use your better judgment here. After you have soaked the plants in the bleach solution, use your fingers or a fine brush to rub debris off the plants.
Afterwards, make sure to use some warm water to rinse the plants off thoroughly. Soak the plants in clean warm water for 10 minutes, then rinse them off again as well. You definitely want to make sure that there is no remaining bleach on the plants when you put them back into the aquarium because that could make your fish very ill or even kill them. You can actually use this method for fake aquarium plants too.
