When it comes to algae
control and water clarity you have two choices in dealing with it:
Artificially or Naturally.
Artificial methods include algaecides
and chemicals that kill any and all life in the water, similar to filtering a
swimming pool. These methods are best used in formal fountains and some indoor
water features where plants and fish are not desired.
Natural methods include
plants, fish, and good bacteria that work with Mother Nature, not against her.
Since the majority of pond owners are interested in both plants and fish we have
chosen to elaborate more on the natural ways to ensure a healthy well balanced
Tips & Facts On Controlling Algae Naturally
Algae is a plant, it requires nutrients and light to grow.
When you add
aquatic plants to your ecosystem they directly compete for the nutrients
available. Add enough plants and you naturally minimize the nutrients.
If your pond contains few or no plants and you are experiencing
algae, adding plants should be one of the first remedies tried.
- Overfeeding fish:
Feed your fish less than you would like. Undigested fish food is the primary
pollutant in many ponds. Your fish consume many things in the pond including
algae. Excessive food increases waste and nutrients that feed the algae. Ponds
overloaded with to many fish also become harder to keep in balance. During
algae blooms reduce or eliminate feeding until it is under control.
- Reduce sunlight penetration: Cover
at least 50-60% of the surface area of your pond with plants. Bare expanses of
water are much more difficult to keep in balance than ponds filled with
- Add bacteria:
Routinely introduce good bacteria into your ecosystem. Larger doses when
cooler water temperatures are present and monthly during the warmer months.
Healthy colonies of bacteria play an important part in ensuring a naturally
- Circulate and filter
the water: Pulling water from one
end of the pond and filtering it before
it returns at the opposite end will greatly improve water quality. Beneficial
oxygen is added to the water as it is circulated. A filter may solve the
problem if you have tried other methods unsuccessfully.
- Control runoff:
Excess water runoff from lawns and perimeter gardens will overload the pond
with nutrients and is not good for aquatic life. A slight birm of dirt sloped
away from the pond will greatly reduce runoff. Drain tile may also be used in
- Remove debris:
Decaying leaves and plant debris will produce excess nutrients in your pond.
Manually remove decaying aquatic plants and their leaves. A skimmer is by far
the most efficient and low maintenance way to keep your pond free of debris.
- Water change: A partial water
change (20-30%) every 4-6 weeks may help reduce excess nutrients in some
Conclusion: There are many ways to head
off and control the invasion of algae. This article should be used as a guide
only. It is our intent to supply some ideas that should give you a better chance
in getting rid of or stopping it before it begins although we canít guarantee
it. If more advice is needed we recommend researching the internet and talking
to fellow pond keepers, who are always willing to help. No matter what you
read or hear, if it works for you and your pond, it works.
