HOW TO Get Rid of Aquarium Algae

Get Rid of Aquarium Algae in Five Steps


Aquarium algae can be a real nuisance, turning your pristine aquarium into a green and slimy mess. However, there are several ways to tackle this problem and keep your aquarium clean and healthy. Excessive algae growth can cause a range of problems in aquariums, including reduced oxygen levels, pH imbalances, and reduced water clarity. Additionally, certain types of algae can be toxic to fish and other aquatic animals if they overgrow and decompose, leading to illness or death. To prevent these issues, it’s important to maintain good aquarium hygiene and control algae growth through regular cleaning and proper care.

Physically Remove Algae

One of the simplest ways to get rid of aquarium algae is to physically remove it. You can use an algae scraper or magnetic algae cleaner to scrape off the algae from the sides of the tank. This is a great way to remove algae that have already grown, but it’s not a permanent solution. You’ll need to continue removing the algae regularly to prevent it from growing back.

Change the Water

Regular water changes can help to reduce the number of nutrients in the water that algae feed on. This can be an effective way to prevent algae from growing in the first place. Experts recommend changing around 10% to 15% of the water in your aquarium every week.

Make Lighting Adjustments

Algae thrive in bright light, so reducing the amount of light your aquarium receives can help to control algae growth. You can reduce the amount of light by using a lower-wattage bulb or by reducing the amount of time the light is on each day.

Add Algae-Eating Fish or Animals

There are several fish and animals that eat algae, and adding them to your aquarium can help to keep algae growth under control. Some of the most popular algae-eating fish include Otocinclus catfish, Amano shrimp, and Siamese algae eaters. These fish can help to keep your aquarium clean and healthy.

Use Chemical Remedies

If all else fails, you can use chemical remedies to get rid of aquarium algae. OZPOLISH De Algae is a safe and effective algaecide that can be used in fish tanks. However, it’s important to follow the instructions carefully and not overdose. When starting up an aquarium, it’s recommended to wait at least three months before using an algaecide.

Making use of mild algaecides, such as OZPOLISH De Algae, can eliminate many types of aquarium algae without harming any scaled fish, but they do not prevent the growth of new algae. To accomplish this, one straightforward method is to enhance the population of beneficial bacteria in the tank, which can be accomplished through the use of the OZPOLISH Bio-Cure. These bacteria can compete with algae for nutrients and space, helping to suppress its growth.

Prevention is Key

Preventing algae growth is easier than getting rid of it, so it’s important to maintain good aquarium hygiene. This includes performing regular water changes, avoiding overfeeding your fish, and ensuring that the water is sufficiently filtered and oxygenated. It’s also important to avoid adding too many fish to your aquarium, as this can lead to overfeeding and an increase in nutrients in the water.


Getting rid of aquarium algae can be a challenge, but by following these tips, you can keep your aquarium clean and healthy. Remember to physically remove algae, change the water regularly, make lighting adjustments, add algae-eating fish, and use chemical remedies only as a last resort. By taking a proactive approach to aquarium maintenance, you can enjoy a beautiful and healthy aquarium for years to come.
