Algae is a type of bacteria found in many places such as ponds, lakes, and oceans, but it can also grow in your fish tank. Although virtually every fish tank has some type of algae growing, too much of the bacteria can cause problems to your fish and aquarium plants if it gets out of control.
The most efficient way to clean aquarium rocks of algae is by using a vinegar solution. This method helps to eliminate algae and calcium buildup, as algae often draw calcium and other minerals from seawater for food. You can also use hot water and bleach to remove debris and algae from your decorative rocks.
The exact method you need will often depend on algae growth and whether you have sensitive aquarium plants in your fish tank. This article will explore the various methods of removing algae from aquarium rocks.

How To Clean Aquarium Rocks Of Algae Using Bleach
Algae in your aquarium can come in many forms: red, blue, green, black, or white. It can also appear puffy, mossy, or stringy. Whatever it looks like, you need to get rid of algae in your fish tank as soon as you see it. Even if it looks little today, it has the potential to colonize your entire tank given the right conditions. Here are a few steps to use bleach to clean your aquarium rocks and other tank decorations of algae.
- Remove the aquarium rocks from your fish tank. Be sure to remove the decorations gently and one at a time to avoid stressing out your fish. You should also be careful not to knock off and release algae directly into the water.
- Expose the substrate by moving all live plants to one corner of the fish tank. Clean any rocky substrate debris using a gravel vacuum and aquarium siphon.
- Place the aquarium rocks and other decorations in a pot of boiling water and leave them there for about twenty minutes. The hot water should be enough to kill off most of the algae.
- Scrub the decorations thoroughly with a toothbrush, reaching all the nooks and corners to eliminate as many algae as possible.
- In a bucket, prepare a bleach solution with 5 percent bleach and 95 percent warm water. Put on gloves to avoid burning your hands, and then soak the aquarium rocks in the bleach solution for about five minutes. Scrub the decorations once more using your toothbrush.
- Rinse the decorations thoroughly with cool water, then again with warm water. You want to ensure no bleach remains on the rocks when you put them back in the fish tank, as it can present serious health problems for your fish and plants.
If there is an issue with chlorine in your water, you can easily neutralize it with a dechlorinator. Simply add dechlorinator to a bucket of water and soak the rocks for a few minutes before you put them back in the fish tank.

How To Remove Algae From Aquarium Rocks Using Vinegar
Removing algae from smooth aquarium rocks is relatively easy, but you need a different solution when working with rocks that have rough surfaces. This is where vinegar comes into play. Vinegar helps eliminate mineral deposits typically left behind when hard water evaporates, and it can also double as an effective disinfectant for your fish tank.
Method 1
In a plastic bucket, prepare a vinegar solution using water and white distilled vinegar in a 1:1 ratio.

Soak your aquarium rocks in the vinegar solution for at least 24 hours. The algae should be dead after one day.
Next, wash the rocks properly to remove mineral residuals and set them aside to dry.
Note: Do not dip your rocks in vinegar if they are made of calcium carbonate. Vinegar is an acid that will dissolve bits of calcium carbonate in the rocks to release carbon dioxide.
Method 2
Get a new toothbrush or one of these algae brushes:

How To Remove Green Algae From Aquarium Rocks With Hydrogen Peroxide
If your aquarium rocks have been infested with stubborn green algae, you should be able to get rid of it with hydrogen peroxide.
- Combine freshwater with hydrogen peroxide in a bucket.
- Soak your aquarium rocks in the hydrogen peroxide solution and leave them for a few hours.
- Rinse the rocks properly and set them aside to dry.
Hydrogen peroxide has numerous aquarium applications when used properly, but you should always consider it as a last resort only after the other methods have failed. This is especially true if your fish tank contains certain plants such as Riccia fluitans (liverwort) or Riccardia sp. (coral moss), which are highly sensitive to hydrogen peroxide.
The recommended dosages of the 3% hydrogen peroxide solution for the different green algae species are:
- Blue-green algae – 8-15ml per 50 liters of water
- Green algae – 25-35ml per 50 liters of water
More algae in your fish tank mean more nutrients being sucked out of the water. The result is that your aquarium plants will not get enough nutrients, which they usually absorb through the substrate and water column.
Excessive algae in your aquarium make the water appear cloudy, and virtually everything looks dirty, which is not attractive. Moreover, a big algae bloom comes with increased resource demand, which may be too overwhelming for your filter to handle.
Once you know how to clean aquarium rocks of algae, you can regulate the growth of algae on your aquarium rocks and other decorations. Some level of algae is not all that bad for your fish tank, especially if you are looking to create a serene environment for certain types of fish such as betta. Just be sure to keep the algae under control and clean your aquarium every now and then.
