Algae Control Options


If algae is a persistent problem in your pond, of if it occurs later in the year, chances are there is an imbalance in the pond.  The most common reason for any algae bloom is excess nutrients, extended sunlight, warm water temperature, as well as high phosphate and CO2 levels.  Be assured that these problems are not as difficult to resolve as many pond owners believe.  When algae becomes a problem for your pond try these control options.

Your first control step
Before you can begin to control algae, you need to understand the chemistry of your pond.  Begin by purchasing a quality test kit to reguarly test the nitrate, nitrites, and phosphate levels.  The use of a pond thermometer to track water temperature changes is also helpful.  Some algae products should be used when the water temperature is above 60 degrees.

If nitrate levels are  high, or if there are nitrite or phosphate present, you have several options for controlling algae.  All can be effective depending on the conditions, but sometimes a combination of options is the best way to proceed.

Additives
There are a number of products available on the market today to control algae.  Liquidicon, dry granulated, and shade products are available to control algae.  Choose the product on ease of use, effectiveness, and control of algae without harming your fish or plants.  Although there icon are many products on the market, the one I use most in my pond is Algaefix.  One 16oz bottle will treat up to 4800 US gallons.

When using Algaefix or any algae control product be sure and follow label directions.   Remember, too much of a good thing can produce bad results.  As the algae begins to die off, it can quickly deplete the supply of oxygen in your pond.  Warm weather will also reduce oxygen levels killing fish, so be especially careful when using pond additives to control algae during the summer months.

As any algae product will take time to work, (usually around 3 days), be sure and add filtration, or do a water change rather than increase the dosage.

Filtration
One proven, safe, and effective way to remove floating algae is a UV sterilizer.  Installed in your iconiconpond, a UV sterilizer can reduce waterborne algae in your pond by as much as 99%.  Another benefit is the cleansing effect of a UV sterilizer.  Many harmful biological organisms are eliminated with UV sterilization.   The multi-function UV sterilizer shown at right is for pond up to 1000 gallons and will effectively kill free floating algae and bacteria.  If you are looking for an easy and effective way to reduce algae and eliminate harmful organisms from your fish pond,  try this UV sterilizer.

Plants
Plant water lilies to provide shade.  Water lilies and other pond plants, not only provide shade but they also feed on the same nutrients as algae.  Pond coverage should be at least 75% of the water's surface.  These beautiful firecrest water lilies would make an attractive addition to any pond or water garden.  What a lovely way to provide shade and add protection from predators to your pond!
