Filtration is one of the most important
components to a koi pond, goldfish pond or water garden though many treat
filters like an option instead of a necessity. If you want clean and
healthy pond water you MUST have some sort of filter. How effective
the filter is depends on many factors - size of the filter - media used -
how it's plumbed into the system - amount of fish load - size of pond - ...I
really could keep going...
There are basically two kinds of filtering -
Mechanical and Biological - and sometimes both filtering methods are rolled
into one filter. Mechanical filters remove debris from the water.
Biological filters house nitrifying bacteria. Both utilize the same
filter media. The media traps dirt and other debris and sifts it from
the water as the water runs through it and the same media gives housing to
good nitrifying bacteria. Most the time we find that the amount of
filtering media is not enough to support the fish load of the pond and give
adequate mechanical filtration. Top of
the line bead filters, like our ProBeads, are designed to give you the best
mechanical filtration and biological filtration available on the market while
providing low-maintenance design, especially when paired with a blower / bead
agitator -- making them the choice for the koi pond keeper who has little time
to spend cleaning pads. Mid-range filters, like TetraPond Pressurized
Filters, offer low-maintenance design with adequate mechanical and biological
filtration for smaller goldfish ponds and water gardens with very light fish
loads. Although they are less expensive than bead filters they are less
quality, do not give the superb filtering, and do not last as long as the
higher-quality bead filters.
