Algae is probably the single most annoying occurrence
in the search for clear water. It is important to understand that
there are a couple different types of algae.
Green
water or waterborne algae is quite common. This algae comes in the
form of tiny free-floating
particles which give the pond water a green cast. Using Accu-clear
& Pond-zyme can be all you need to control these outbreaks. If not
then adding a UV sterilizer will most definitely
put an end to that.
Algae-bloom or stringy-algae is a creature of a
different color. This homely growth starts at the bottom of the pond
and grows upward till it reaches the surface where it then expands into
a floating bubbly pad of goo. It will grow from the bottom or from the
side walls of the liner. Don't be too alarmed, the presence of stringy
algae usually indicates that you have a healthy pond but it's just not
a pleasant feature to look at. As it is not a free-floater it doesn't
make it's way into the UV and other means of removal become necessary.
There are a couple different ways to combat this slimy
mass. The age-old time-tested way is to limit the amount of sun that
reaches the bottom and sides of the pond. This is done by keeping at
least 50% to 75% of the pond surface covered with floating plants such
as water lilies,
water lettuce and water Hyacinth. Another very old fashioned but
highly effective method of hindering this growth is Barley
Straw.
This product has been used by farmers in the UK for centuries and has
recently made a comeback with the popularity of water
gardening. It is only harmful to algae and posses no threat to fish or
other plants. The barley is added to an area of moving water in very
early spring. It must begin to decay before it will become useful.
Typically a second treatment is added midsummer so that the two
treatments overlap. The product is left in the water until it is
completely disintegrated. Barley concentrates
are also available in the form of pellets and liquids.
Another effective product to fight algae is Microbe-lift.
This product works much like Barley. It is a liquid that is added on a
regular basis which inhibits stringy algae growth. It also purifies by
aiding in the digestion of foreign matter. Microbe-lift is also
available in a winterizing formulation.
