A lot of people have been asking about why coralline algae are turning white, or why it turns white. If you are one of these people, then this blog post is perfect for you! We will discuss the process behind what causes coralline algae to turn white.

Coralline algae are single cells of the genus Ostreococcus, which is a type of marine microalgae.
The name comes from their unique position in the food chain: they eat bacteria that would otherwise produce greenhouse gases like carbon dioxide or form sulfuric acid as a byproduct.
They are white because they have large amounts of chlorophyll-b, which allows them to grow fast and break down these harmful chemicals quickly.
However, when there are too many nutrients and minerals present (e.g., when ocean levels rise due to climate change) then these algae will start eating coral reefs instead of just bacteria!
Coralline algae – or more simply called white coral are a type of zooxanthellae that are commonly found in the Great Barrier Reef.
From time to time, these small microscopic creatures can turn from their normal colors and start to bleach out, becoming paler than ever before. But how do they get this way?
The increased temperature levels cause corals to expel their zooxanthellae and push them out into the ocean water, causing the dark matter to grow duller and whiter over time. If left untreated for too long, these algae will die off completely, leaving our reefs with nothing but grey skeletons behind them.
What are coralline algae?
Algae is a common and natural occurrence in saltwater aquariums. It can grow on glass, rocks, substrates, or even on submerged plants.
Algae is not harmful to the fish as it doesn’t produce any toxins that will harm them; however, if you have too many algae in your tank it can reduce light penetration and lower oxygen levels for your fish.
Some of these types of algae are Cyanobacteria, which produces cyanotoxins that can be lethal to aquatic life when ingested by filter feeders such as clams and oysters.
Reasons why coral line algae turns white?
The pH level of the water in our oceans has been steadily increasing. And as a result, coralline algae is turning white. Coralline algae are usually greenish-brown and red in color but with the increased acidity in seawater, they’re turned white.
Scientists are very concerned about this because if this trend continues then there will be less food for fish and other lower marine life that depend on coral line algae to survive.
- Coralline algae are turning white because it’s dying
- The stress of the environment can cause coralline to turn white
- White patches on coralline are caused by a bacterial infection, which will eventually kill off the algae
- Coralline that turns white from being overfed with nitrates and phosphates may be saved if you stop feeding it for a few weeks
How long does it take for coral line algae to turn white?
In the summer of 1951, Dr. John T. Gulick was an undergraduate at the University of Hawaii when he observed a large-scale die-off in coral reefs of Kaneohe Bay on Oahu Island, and theorized that it was caused by an increase in sea temperatures due to global warming.
His studies found that increased water temperature can cause corals to expel algae from their tissues leading them to turn white, which is called Coral Bleaching.
Coralline algae is a type of algae that lives in the ocean and it turns white when it dies. Algae are organisms that use sunlight to make their food and they need nutrients from other sources like minerals, nitrogen, or small animals called zooplankton. Coralline algae turn white when they’re starved for these nutrients.
How to prevent coral line algae turning white in your tank
Coralline algae can be found in freshwater tanks. When it turns white, it means the tank has been polluted by the presence of excess nutrients or other toxins. The best way to fix this problem is to remove excess food and give the aquarium 20-30% water changes on a daily basis until the pollution clears up.
How to grow coralline algae in your aquarium
Coralline algae are one of the most important types of marine life in an aquarium as they can help to create a natural balance for your saltwater tank. Coralline algae will help with water clarity, and also provides food for other aquatic organisms living in your saltwater tank.
There are a few things you need to know about coralline algae before you start trying to grow them yourself.
They prefer areas where there is not much light exposure but still get enough indirect sunlight through the day.
They prefer warmer water temperatures than those found at depths below ten meters from shorelines or reefs according to the NOAA Fisheries Office of Science and Technology which studies corals and fish habitats across America’s coasts.
Coralline algae will grow in your aquarium as long as the water and temperature are right. The process of how to grow coralline algae is quite easy, but it takes patience.
Coralline algae can be grown from live rock or from dry rock that has been soaked for about 10 days before adding to the tank. It only needs light and food because they photosynthesis like plants do.
The coralline algae is a natural and beautiful addition to any aquarium. It can be grown in your tank with the right conditions, but it might take time if you are new to aquascaping.
Can coral line algae return it’s normal colours from white?
I get asked this question a lot and the answer is that it will depend on what has happened to it. Coralline algae are in danger of dying out due to climate change, pollution, and over-fishing.
The healthy corals are starting to disappear too because they cannot survive without them. However, if someone took care of their coralline algae in their own tank then I’m sure they could have a rainbow once again!
In the aquarium hobby, it’s not uncommon for coralline algae to bleach out or turn white. This is what happened with your tank because you most likely made a sudden lighting change that was too intense and bleached the red pigments from their tissues.
However, they are pretty hardy little critters so don’t worry! The color may take anywhere between 2-6 weeks to return depending on light intensity but if this doesn’t work then I would recommend moving them back into lower light conditions until things get better again.
summary
Whether you intend it or not, sometimes coral line algae will grow in your tank. As mentioned previously, it all depends on conditions.
they can be at sea, or in your own personal tank that you can witness. I hope you have learned all about coralline algae, and what to do to get it, prevent it, and everything else in-between.
