What
has happened?
Visible string algae, often in dense bails looking like felt, develop if
the natural competitors for nutrients, the water plants are missing
totally from a pond, lacking or lacking in variety. Phosphate, the stuff
algae are made out of, gets into the pond with the rain and with food and
can hardly be removed. In contrast to the algae bloom where tiny protozoan
give the water an even green colouring, the string algae actually indicate
a rather good water quality.
What
can happen?
String algae can spread very rapidly. They preferably settle in moving
water such as water courses, rock fountains etc. Sensitive underwater
plants are literally crushed to death.
What
has to be done? You can try to 'fish out' the string algae but if that
is not sufficient and you would like to clean out the pond completely try
"String algae
control", which will show a relatively quick improvement. The algae
will disappear even quicker if additional means are applied such as
stabilising the water, adding pond plants, particularly floating plants
and so-called oxidising plants. For a successful treatment with "String
algae control" the water hardness must be increased to at least 5° dKH
with the help of "Hardness
plus". (Test the water!!) "String
algae control" works particularly well during the vegetation period.
You can often see string algae appear already in early spring when the
water is still cold but clear.
Will
the string algae stay away?
Only if the lack of nutrients is permanent. A pond with fish will hardly
be able to do without the odd algae cure with "String
algae control". A useful help in reducing the nutrients are suitable
pond substrates such as zeolite, which will remove nutrients before they
become soluble.
Tip:
Exchange unsuitable pond soil rich in nutrients with suitable pond
substrates.
