Types
of Algae
If
you notice these algae is growing in your aquarium, then you need to get rid of
it. First you need to know the type of algae you have. Take a look at the
common algae types:
Blue-green algae: other names are slime
or smear algae, it can be caused by an excess of nitrate and phosphate in the
water. Actually, this is not algae at all, but cyanobacteria. It can spread
rapidly and can be difficult to control. Good water care will help. But if your
water source has phosphate, you may have to use special treatments to remove
the excess nutrients. Erythromycin is effective against blue-green algae, but
use it carefully, it will likely harm the beneficial bacteria colony in your
bio filter, too.
Brown algae: This is known as gravel
or silica algae, these algae are very common in new tanks, which are easily
wiped off. It is usually harmless and will eventually go away as the tank
matures.
Red or beard algae: This is one of the
toughest algae to get rid of, and it usually appears on plants and decorations.
A dip in a weak (5 to 10%) bleach solution for a few minutes will often kill
this type of algae. But use this bleach solution very carefully.
Green algae: This is also known as
hair algae , thread algae , or spot algae. It is a healthy type of algae that
every tank will most likely experience to some degree. As long as the tank is
well cared for, it will grow very slowly. Try to add some of Algae eater fishes
in your aquarium for control these algae.
Green water: This is also known as
an algae bloom, this is caused by the growth of microscopic algae that are
suspended in the water. Generally, water changes are not effective, as the
remaining algae will quickly grow back. It is one of the more frustrating types
of algae to remove as it cannot be wiped or scraped off like other algae. Use
of a diatomic filter or completely blocking all light for several days is
usually necessary to conquer green water. Test the water to be sure it does not
contain any ammonia, nitrite, nitrate or phosphate.
