How does algae grow in hydroponics?
Like any other plant, algae live by photosynthesis. There can be no algae in total darkness, but in a hydroponic system, they usually find enough light to survive and sometimes proliferate. Algae can also be seen in soil and coco grows if the medium is constantly moist, but only on the surface.
How does algae removal work in aquaponics?
Shading: Like in aquaponics, shading algae will starve them of light. UV filters (clarifiers): UV filters consist of a plastic or steel cylinder with a lamp housed inside. In that lamp is a filament that produces UV light. This light sterilizes the water flowing around it, destroying bacteria and algae.
Why is algae growing in my hydroponic system?
Since algae are plant-like, your hydroponic system can be the best environment for algae growth. Warmer temperatures, nutrients, water, and light is what algae need to grow. Light reaching hydroponic rich water starts the growth of algae. Once it starts, algae spread can reproduce rather quickly.
Is algae a problem in hydroponics?

Why do hydroponic systems have algae?
Algae create several issues in hydroponic systems. The first problem is mechanical. Algae reproduce on any surface. Once in the system, it can work its ways into any tube or pump, resulting in clogging and causing the system to run sluggishly or break down. Eventually, it will cause the system to quit working entirely .
How to manage algae?
The first part is preventing as much algae growth as possible. The most effective way is preventing sunlight from reaching the nutrient solution and growing medium. If there is no sunlight, the algae cannot grow. All parts of the system that house water or the nutrient solution need to be opaque to prevent light from reaching the liquid.
Why is it important to clean your growing area and not just your hydroponic system?
It is crucial to completely clean your growing area and not just your hydroponic system because algae spores are moved around by air.

Shading is the easiest method to reduce algae in your systems. Green algae need light to grow and reproduce, so to get rid of them easily, simply shade your fish tanks with a dark colored tarp or piece of plastic.
Why do algae cause pH swings?
These swings are called diurnal pH swings. Algae cause pH swings because they consume CO2 during the day when the sun is high and photosynthesis is at its peak.
What are the problems with suspended algae?
But there are two main problems with algae that especially need to be addressed: 1. Oxygen depletion. 2. pH swings.
What happens when algae decomposes?
Oxygen consumption happens when dead algae begin to decompose. This isn’t usually an issue if it happens in grow beds or other aerobic environments. It really is an issue when it happens in the fish tanks or other aquatic environments.
Why does algae have low oxygen levels?
The second way that algae causes problems with oxygen is that they can die off or accumulate in grow beds and consume oxygen. This leads to dangerously low levels of oxygen when electricity or circulation fails . (Decomposition of algae isn’t typically a problem in aerobic environments.)
What is the most common algae in aquaponics?
The algae that occur in most aquaponic systems and cause the most problems are green algae.
