Clean - Clear - Healthy Water:
Ponds are ecological systems in which many factors form a
well-adjusted equilibrium. If the pond has too much nutrition (e.g.
through leaves etc), the balance is upset. The consequence: the
water becomes cloud, it changes colour and becomes contaminated.
Helps clear algae:
When the weather is warm and there is sufficient nutrition,
floating and threaded algae increase rapidly. All this leads to the
pond as am ecological system becoming unbalanced. The water becomes
cloudy, and the other plants do not get sufficient light and die
off.
Biologically pure water without chemicals:
Fighting against excessive nutrients by using chemicals can be
dangerous. Depending on the composition of the agent, the biological
system can be seriously damaged and toxic materials can be generated
unintentionally.
Less cleaning required:
Conventional pond filters need regular care: depending on the
load they have to be cleaned more or less regularly, and this takes
time and is dirty work. |
