Cleaning Aquarium Rocks With Vinegar

Last Updated on November 9, 2021 by Marco C.

It’s incredibly important to keep your aquarium decorations clean, and cleaning aquarium rocks with vinegar is one way to do that. Many aquarium owners have trouble finding ways to keep their aquarium clean. This can present a problem because hygiene is crucial for the health of your fish. However, there are many ingenious ways of keeping your fish tank clean!

How To Clean Rocks For An Aquarium

Rocks are the most common aquarium decoration and keeping them clean is key. They can easily grow algae and other things we don’t want. There are, however, many methods you can apply on your rocks to keep them clean!

Sponge and Warm Water

This is a default method for cleaning pretty much everything in our everyday lives. Most dirt on your aquarium rocks can be washed away by scrubbing the rock with a sponge and some warm water. You shouldn’t use soap when you’re doing this, as the rocks have to go back in the aquarium and the soap may not wash away properly.

Know that most chemicals we use in our everyday lives are harmful for fish!

It’s also not recommended that you use any sort of mechanical washer for your rocks.

The Bleach Method

If you’re wondering how to remove algae from fish tank rocks, then the bleach method should do the trick! For this method, you’ll need bleach, water, and a sponge. You should mix the water and the bleach in a 9:1 ratio (9 cups of water for every 1 cup of bleach). After mixing that in your bucket, place the rocks inside.

Let the rocks rest for 15 minutes, after which you’re free to scrub them clean. This method is useful when the algae already grew multiple layers – most young algae can be washed with a sponge and warm water.

After scrubbing the algae off, put the rocks in clean water and let them rinse for 15 minutes. After that, let them dry and put them back in the aquarium after drying. Know that it can sometimes take up to three days for them to dry.

The Muriatic Acid Method

This method is useful when tackling particularly difficult tasks! For example a buildup of phosphates, which are especially common with saltwater aquariums! However, muriatic acid is very strong, so take special care when you’re working with it. This acid is available at most pool shops!

Firstly, know that this is a hazardous chemical, so be careful! Put the rocks in a bucket and make a mixture of 9:1 (water to acid) and watch the bubbly reaction. This reaction will last for about half an hour, so you’ll have to wait for it to end. Once the reaction has finished, add baking soda to the mixture. Keep adding baking soda until the pH of the water is about 7, only then can you get rid of the mixture safely.

Rinse the rocks with water and let them dry for a few days!

Cleaning Aquarium Decorations With Vinegar

The vinegar method is a popular method for cleaning a lot of aquarium decorations, not just rocks!

It’s particularly popular for calcium buildup and it’s much safer than muriatic acid. You should use this method for smaller, less advanced problems! You can use vinegar to clean rocks, the tank, the filters, the heater, and other decorations (driftwood, etc.).

To clean with this method, make a 1:1 mixture of vinegar and water. We recommend that you use a very large bucket for this, so you can fit all the decorations at the same time. Feel free to let them soak in the mixture for hours – vinegar won’t harm them.

After you’ve taken them out, rinse all the items in freshwater. Once again, let them dry on their own and return them to the aquarium.

If you’re facing more difficult problems, you can use an even stronger solution of water and vinegar. For example, if the buildup of calcium on one of the rocks is particularly bad, you can try a 1:2 (water: vinegar) solution for that rock, just make sure to rinse it well once you’ve finished.

Most minor issues can be solved with this method, but for more advanced buildup of calcium and algae, you’ll have to use more aggressive methods, like the muriatic acid method.

How To Prevent Algae, Calcium, and Phosphate Buildup

The best solution to the problem of algae, calcium, and phosphate buildups is preventing them!

It’s impossible to completely stop the buildup of these, but it’s entirely possible to slow it down significantly.

The most important thing is tank maintenance – making sure that your filters are working properly is key. Your filters are going to get bogged down every once in a while, and it’s important that you clean them on time. This way, they’ll be able to filter the filth out of the water properly.

Following that, you need to change your water frequently. How often your water needs to change depends largely on the size of your tank, but it’s necessary to change your water per schedule!

Use test strips regularly to monitor the state of your water. This is particularly important for your pH levels!

For phosphate, you should check what food you’re using. Phosphate is commonly used as a preservative in fish food, but not all manufacturers use it. You should also remove all uneaten food quickly, and make sure not to overfeed your fish. Lastly, try different filter media – there is filter media made to stop phosphates from invading your tank!

In conclusion, cleaning aquarium rocks with vinegar is an effective cleaning method! It’s particularly useful when you’re facing minor buildup of calcium and phosphates. However, if you’re having a lot of trouble with cleaning your rocks, you should try the bleach method or the muriatic acid method. These methods use more aggressive compounds to clean the rocks.

The best method, however, for cleaning your decorations and equipment is regular maintenance! 

Keep your aquarium equipment and decorations clean, change your water on schedule and you’ll slow down the buildup of calcium and phosphates significantly!
