Make sure you really get every last particle free; black algae has particularly long and stubborn roots which makes it a persistent strand.
What eats blue-green algae?
Algae are eaten by zooplankton, which are in turn eaten by small fish, then larger fish, and eventually the larger fish are eaten by birds, shore animals, and people.
Microcystis
Appears rapidly, initially appears white and soapy, then becomes like spilled paint or pea soup. It creates a smelly blue-green oil scum at the surface.
Aphanizomenon
Commonly found growing with Microcystis (both can cause skin irritation). Has an appearance of tiny grass clippings floating in water.
Anabaena
Appearance almost identical to Microcystis’ pea soup coloring, except Anabaena is filamentous and doesn’t migrate. The microscopic visual difference is a thicker cell wall than Microcystis. Occurring in phosphorus rich waters, Anabaena produces toxins which can kill pets, wildlife, and livestock.
Oscillatoria
Split into floating mats or attached to rocks, Oscillatoria appears in colors of dark blue-green, dark red, brown, green-black, or purple. May show an oscillating movement. Can produce toxic microcystis in certain strands.

Once the blue-green algae is removed, this level of nitrates should prevent it from coming back. Like most algae, a well-maintained tank with stable water parameters seems to be the best method of preventing blue-green algae from taking over your tank.
Why does blue green algae appear in my tank?
Some say that the cyanobacteria is present in the local water supply, and is introduced into your tank during water changes.
What would happen if cyanobacteria didn't exist?
That’s right, it was around well before dinosaurs roamed the earth. [ 2] Many scientists believe that if it wasn’t for the formation of cyanobacteria, humans may not exist! Also, cyanobacteria are able to photosynthesize – that is, use light to create food. This is something typically only seen in plants.
Why does my fish tank smell?
In fact, blue-green algae might be the reason why your fish tank stinks! If I had to describe the odor, I would have to say that it smells similar to rotting plants – like a swamp. However, not all types of blue-green algae have a scent.

Why is cyanobacteria called cyanobacteria?
As you see, cyanobacteria is named because of how it looks under a microscope, a lovely shade of cyan, which is a greenish-blue color. But for the purpose of this guide, I refer to cyanobacteria as blue-green algae.
Why is pond scum called BGA?
You might hear it referred to as BGA, green slime algae, smear algae or even pond scum because of the way it can build up on the surface of ponds. [ 3] It is worth mentioning that the blue-green algae floating on the surface of your pond (pond scum) is different than the blue-green algae in your aquarium.
Can zooplankton eat blue green algae?
Biological Management Options. While many microscopic animals (zooplankton) eat Blue-Green algae, there are no practical ways to increase their populations , so no biological control is possible.
Can oxygen depletion kill fish?
One danger with any chemical control method is the chance of an oxygen depletion after the treatment caused by the decomposition of the dead plant material. Oxygen depletion can kill fish in the pond.
Is copper toxic to fish?
All copper compounds can be toxic to fish if used above labeled rates and can be toxic in soft or acidic waters even at label rates. Before using copper it is best to test the pond water’s alkalinity and adjust copper treatments to alkalinity concentrations.
Do herbicides have restrictions on water?
Many aquatically registered herbicides have water use restrictions (See General Water Use Restrictions ). To see the labels for these products click on the name. Always read and follow all label directions. Check label for specific water use restrictions.
Is copper sulfate a hard water solution?
Smaller crystals will dissolve easier than larger crystals. In very hard water it is difficult to use copper sulfate because it binds with the calcium, precipitates out of solution, and renders the co pper ineffective as an algaecide.
How does blue green algae kill fish?
Blue-Green Algae can easily cause fish kills by absorbing oxygen to survive and depriving fish of the oxygen they need to survive.
What does blue green algae look like?
Blue-green algal blooms are often described as looking like pea soup or spilled green paint. However, blooms aren’t always large and dense and can sometimes cover small portions of the lake with little visible algae present. Blooms can also produce a swampy odor when the cells break down. Here are some examples of algae blooms.

What is blue green algae?
What is Blue-Green Algae? Blue-green algae (BGA) is not actually an algae but rather a cyanobacteria – a very diverse and resilient group of bacteria that uses photosynthesis like plants. In freshwater aquariums, it’s known for its vivid blue-green color, but it can also appear in shades of brown, black, or even red.
How to identify blue green algae?
Another way to identify blue-green algae is by its distinct odor. People have described the smell as earthy, musty, swampy, and foul. Once you have learned to recognize the scent, it’s possible to detect cyanobacteria up to two weeks before it’s even visible in the fish tank.

The species which are particularly troublesome to control are those which grow in colonies forming small spongy masses of mucilage. These blue-green, black or gray clumps made up of thousands of individual cells will lay on the bottom or float to the surface. Because of the protective mucilage, chemical control is difficult.
What is blue green algae?
What is Blue-Green Algae. Cyanobacteria, commonly known as Blue-green Algae, is spreading across North America at rapid rates due to increases in nutrient pollution. Despite its name, blue-green algae is not technically a form of algae, it’s bacteria. Algae is made up of eukaryotic celled organisms and cyanobacteria are prokaryotic.

What is the effect of phosphorus on algae?
When nutrients like nitrogen and phosphorus pollute fresh waters they act as a fertilizer to the cyanobacteria, causing rapid growth resulting in a bloom. Algal blooms release cyanotoxins when they expel energy during reproduction and when they die. Cyanotoxins are extremely dangerous to humans and animals.
Why do cyanobacteria look like algae?
But what causes the confusion of whether cyanobacteria are algae is that they can photosynthesize, which causes them to act like algae. Cyanobacteria sources energy from the sun similar to how algae does and multiplies rapidly to create visible blooms that look and feel like true algae.
How long do cyanobacteria blooms last?
The risks are undeniably high. Toxic algal blooms can last days, weeks, months, or even all year depending on the climate, and toxins can remain in the water long after a bloom has disappeared.
How to prevent blue green algae blooms?
Preventative measures for blue-green algae are similar to those of common plant algae and provide the first line of defense. The main cause of cyanobacterial blooms is the accumulation of excess nutrients in a body of water. The following measures can help prevent a blue-green algae bloom from occurring: 1 Do not overfeed fish or birds; the excess can cause nutrient buildup. 2 Plant and maintain native flora around ponds and streams, which help filter water and don’t require fertilizer. 3 If applicable, properly maintain your septic system. 4 Do not overuse lawn and garden fertilizers, especially near bodies of water. 5 Do not allow pets or livestock to defecate in streams or lakes.
