Algae in the pond, Biofilm

 

Leaves, pollen and other nutrients fall constantly in. More intensive solar radiation sets the photosynthesis and strong alga growth is the result.After the winter break, the flora and fauna must first grow in the pond much properly and the nutrients in the water are higher in multiples than in summer. Suddenly thick alga cushions appear on the water surface.

Algae in the pond
 
Algae is a big nuisance in the pond, garden pond, swimming pond or Koi pond. The ugly sight makes it to a big nuisance, problem for pond owners who enjoy having a cultivated pond.


Causes of algae in the pond, water object: 

  • The very hard water, which can strongly contribute to the formation 
  • Nitrates as an energy source for algae, Biofilm
  • Nutrient surplus in the pond: a reduction in the nutrient content so that the algae do not receive any food 
  • A pond with biological dirt or mud. Turning it up by the fish leads to the fact that the "fertilizer" is activated and favors the development of the thread algae.
  • The fish food, Koi fodder as an energy source for algae, Biofilm
  • With clear water and with the intense solar radiation, the photosynthesis is strengthened and the alga formation is strengthened


How can I get rid of the algae? 

  • With the help of ultrasound against algae: the ultrasonic device sends ultrasonic waves in the water. The ultrasonic generator generates „loud music“ in the ultrasonic area (30-50,000 hertz), which is inaudible in the water for human beings and animals. The vacuum in the middle of the alga cell is torn by the resonance oscillations and the existing algae die out.
  • Take away the nutrients in the peripheral zones, regeneration zones. 
  • Remove the biological dirt and mud from the pond. 
  • Reduce the nutrient amount with a reed basin water plants growing in large-scale.


The following plants and reed types take away many nutrients: 

  • Rooted plants like water lilies etc. take nutrients from the ground 
  • Unterwater plants like watermilfoil, chick weed... take nutrients directly from the water 
  • Floating plants take nutrients directly from the water
  • Reed Cortaderia selloane – up to 2-m height 
  • Reed - Phragmites australis – up to 4 ms high
  • Wide-leaf reed mace - Typha latifolia – up to 3 ms high
  • Reed Kalmus - Acorus calmaus – up to 1.5-m height
