The golden algae, the haptophytes, can produce a number of toxins that impact the gills. Some of the cyanobacteria can have acute toxicity with the toxins they produce. And some euglenophytes or euglena can produce fish-killing toxins . So remember to keep toxic algae on your radar as a fish kill culprit.

But a plague of algae in an aquarium is often a sign of an imbalance or that levels of pollutants are too high . It's unsightly, but too much algae can actually cause problems for fish by raising the pH too high, starving the tank of oxygen at night, blocking filters, and trapping fish.
Why does my fish tank turn green so fast?
“Green Water” outbreaks are caused by a sudden population explosion of suspended algae known as phytoplankton . Unlike other algae species that grow on the glass or objects in the aquarium, green water algae float about the tank and multiply by the billions in a short period of time, in what's known as a “bloom”.
What happens when algae dies?
When algae die, they are decomposed by bacteria, which can remove oxygen from the water, occasionally killing fish . Algal blooms can also make water unfit for even recreational use. These tiny organisms can therefore have a huge impact on health, wildlife and economies that depend on fishing and tourism.

Does high pH cause algae in aquarium?
The aquarium itself will often reveal signs of high alkalinity as well. You may notice a sudden increase in green algae growth on the walls and ornaments in the tank. High pH levels encourage the growth of this algae and slime , which will thickly coat the plants and fixtures, making the water highly toxic for fish.
Does algae reduce ammonia?
The relatively low concentration during summer can be attributed to intense photosynthesis by algae, which removes ammonia . During winter, algae take up little ammonia but the ammonia supply continues, primarily from the decomposition of organic matter that accumulated on pond sediment during the growing season.
Can algae be bad?
Summary. Most algae are harmless and an important part of the natural ecosystem. Some types of algae produce toxins that can be harmful to people and animals . Where these harmful algae grow rapidly and accumulate in a water environment, it is known as a harmful algal bloom.

What happens if too much algae is in a pond?
Trace minerals or nutrients needed by the algae are occasionally used up, causing some or even all, of the bloom to die back temporarily. The resulting bacterial decomposition and loss of normal oxygen production can lead to oxygen depletions and fish kills .
What happens if there is too much algae in a pond?
When it comes to any algaecides, too much of a good thing can produce bad results. For example, killing algae too fast can quickly deplete the oxygen supply in your pond . Oxygen levels can also be quickly reduced by warm weather at this time. As a result, fish may die.
