Servus,
mal ein paar Worte zum Thema Algen aus dem Buch "The Aquarium Plant Handbook" 2002 an dem Takashi Amano beteiligt war.

Whenever algae is observed to be more than its normal proportion, analysis of
the elements such as nitrogen, Phosphorus and Iron should be carried out to
verify whether the outbreak is due to the nutrient imbalance. If this is not the
case, the aforesaid measures shall suffice to circumvent such minor infestations.
Severe Infestations: Major infestation of algae is in the form of green water or
dense growth of filamentous algae and black brush algae on each and every
plant in the aquarium. This can occur in less established tanks especially in
newly set up tanks. Less established plants in the tank and the low density of
bacterial population for the Nitrogen cycle are the main causes for such ourbreaks.
If the same kind of infestation occurs in older tanks, nutrient imbalance could
be the major culprit.
When there is a severe algae outbreak, the remedial anion must be immediate.
CO2 injection must be stopped. A major water change of up to 90% should be done
twice a week until algae population shows signs of decline. Elemental
concentrations especially Nitrogen, Phosphorus and Iron are to be monitored and
checked if they are within permissible levels. It is also advised to investigate
if the concentration of Potassium and Magnesium in the water are at their optimal.
Please refer to the Section on Fertilisation for the corrective measures of nutrient
imbalance. Fast growing platns such as Hygrophila difformis, Hygrophila polysperma,
Ceratophyllum demersum, etc., an act as nutrient sponges. Growing such plants in
the aquarium would help deprive algae of nutrients. As mentioned above, introduction
of algae eating fishes and shrimps are added advantages.
