||String algae and planktononic algae are the two primarily types of algae that
effect Koi ponds and water gardens. One is string like and typically grows
on most anything in your pond. Planktonic algae are what turn the water a
lovely shade of green. The following information is based on what we do to
eliminate and prevent algae.
What Causes Algae ?
I like to keep this simple
Sunlight + nutrition (Phosphates and NitrAtes) + not enough plants +
poor water movement = GREEN STUFF.
Sunlight obviously comes from the sun and the nutrition is a result of fish
waste, dead and decaying leaves/ plants, and decomposed fish food.
Eliminating and Preventing Algae
- Starve the algae with water changes. Water changes reduces
NitrAtes and no matter what method of algae control you choose,
water changes are a good starting point. Unfortunately, water
changes will only solve the problem for a day or two..
- Providing live plants to compete for nutrients. Plants like Water
Hyacinth, Water Lillies, Parrot’s feather and Frogs Breath spread
along the surface f the water, using NitrAtes, starving algae and deny
the algae much needed light from the sun. Other methods of reducing
sunlight exposure include the use of pond dyes. You can find our
- Beneficial Bacteria. “Beneficial” bacteria are a type of bacteria that
is required to not only break down toxic ammonia from fish wastes
into harmless nitrates (referred to as the Nitrogen Cycle) but they also
consume the same nutrients as algae does. Adding beneficial
bacteria starves the algae. Beneficial bacteria also breaks down
sludge build up, on the bottom of ponds and much more. It is
absolutely vital to any healthy pond. Establish beneficial bacteria in
your pond requires it a place to grow such as a biological filter, rocks,
plants, and filter media. Beneficial bacteria “colonize” and typically
take 3-8 weeks to establish naturally. The colonization process can
be jump started with the EZ-2, NITRIFIER, or MICROLIFT.
- Move the water. It is recommended that you turn the water in your
pond one to two times per hour. What that means is if you have a
1000 gallon pond, you should have at least a 1000 – 2000 gallon per
hour pump, with appropriate filtration. Even if you have good water
movement, you can still have ‘dead’ water movement zones. A pond
that is two feet or deeper can have little to no movement in the deeper
zones. Even of you turn your pond water properly; you should use an
aeration device in the deepest zones to move the ‘dead’ water to the
top where it can get properly turned with the rest of the pond water.
We have a large assortment of aeration systems for very small tanks
or ponds to ponds and lakes many acres in size. You can find our
