nutrient sources such as rain water represent a
burden for the pond system. Surface water or run-
off water absorbs the nutrients and carries them
into the pond.

Snails and waterfowl:
Always keep snails and
waterfowl away from the swimpond, as they feed
on plants and insects that play an important role
in the nutrient cycle. In addition snails and water-
fowl stress the pond through excrement. Diffe-
rent pathogens can be introduced into the pond
in this manner, for example cercarien that can
trigger an unpleasant skin rash on humans.
4.
Planting:
Plants absorb nutrients – conse-
quently trim your plants before they store their
nutrients in the pond near the end of the vege-
tation period.
5.
Water quality:
Have your pond water analy-
sed on a regular basis, so that you can react
as quickly as possible to changes in the water
values. The Water Test LM from OASE is
extremely well-suited for this purpose. For
example high phosphate content is a nutrient
medium for string algae and can be reduced
through the use of PhosLess LM.
6.
Edges/seal:
Always ensure that the capilla-
ry barrier is intact, particularly with regard to
plants that can grow over it. In addition indirect
