Types of Aquarium Algae
Types of algae you will find in your aquarium are:
- Green carpet Algae
- Green water

- Red or Beard Algae
Green carpet Algae
This type of algae is the most common; they can occupy the aquarium within a short period if they are not controlled. They don’t only grow on water, you find them on your decorations, rocks, walls of the tank.
This algae though nutritious for guppies is dangerous because they change the color of the water to the murky green. This condition will reduce the amount of oxygen in the aquarium and prevent lights from getting to the fish.
This is prominent in a new aquarium with little or no light penetration.
The presence of this algae will create a brown film sheet at the bottom or sides of the aquarium water though you can wipe this brownish film by gently scrubbing the affected part of the aquarium.
Red or Beard Algae
Unlike brown algae that form brown film sheet, red algae form a layered green carpet grass which can be up to 3cm in height.
