Algae Growth Factors


Algae thrive on light, especially sunlight. It’s essential to ensure that your aquarium or pond isn’t receiving too much direct sunlight. Artificial lights can also contribute to algae growth, so make sure to research the ideal lighting conditions for your aquatic inhabitants. Learn more about how artificial lights impact algae here.


Algae grow in environments rich in nutrients, particularly phosphate and nitrate. Factors such as overfeeding fish, decaying plant material, and poor water quality can contribute to an abundance of these nutrients in your aquarium. Read about the role of nitrates in algae growth here.

Water Flow

Algae tend to do well in stagnant water. In aquariums, ensure proper water circulation with a suitable filter or aeration system. In ponds, consider using a pump or water feature to keep water in motion, which will help suppress algae growth.

Algae-Removal Methods

Physical Removal

Manually removing algae from surfaces using brushes and scrapers can be effective, albeit time-consuming. Regularly clean aquariums with an algae scrubber or a magnetic algae cleaner to keep algae buildup at bay.

Natural Algae Eaters

Introducing natural algae-eating species, such as certain fish and snails, can help keep algae under control. Before introducing them to your aquatic habitat, research compatibility with your current inhabitants. Learn more about algae eaters here.

Chemical Treatments

There are plenty of chemical algae removal products available, ranging from algaecides, like those containing copper, to natural bacteriostatic agents aimed at reducing the spread of algae. Make sure to follow the product instructions carefully and monitor the effect on your aquatic life. Keep in mind that some algae removal products may be harmful to fish, as discussed here.

UV Sterilizers

These devices use ultraviolet light to kill free-floating algae in the water. While they can be an effective method of controlling algae, they may not be suitable for all aquarium setups – read more about the implications of using UV light in aquariums here.

Algae Precautions

Quarantine New Plants

New aquarium plants can introduce unwanted algae, so it’s best to quarantine them for a couple of weeks in a separate container before adding them to your aquarium.
