Solving the Problems with Algae


Make every effort to control algae naturally in your  koi ponds.   Your first step in controlling algae should be to test your water and determine what the algae is feeding on.  If you are going to control algae you need to understand its chemistry and then take corrective measures.   Use of a quality test kit to regularly  check levels of nitrites and phosphates as well as a thermometer to track water temperature.  The use of oxygenating plants and pond scavengers like tadpoles and snails, and mechanical methods such as UV lights can also be effective.  Algae that forms on the surface of your Koi pond can
be removed by using a fine mesh net or by twirling it around a long handled brush.  You can also use a rake.  Just twirl the algae around the brush or rake like you would if you were to put spaghetti on a fork.

If algae continues to be a problem, consider adding one or more filters to your Koi pond system.  Remember the purpose of a filter is to trap particles of matter such as algae that are iconicon suspended in the water.  The Tetra Pond bio-active pressure filter shown at left is a good choice as it is easy to maintain with a simple backflush to keep the filter working at its peak performance.  Fish waste, excess food, and decaying organic matter such as leaves, can all contribute to the algae problem in your Koi fish pond.  A good filter system will work to remove these from your Koi pond, which will help with the growth of excess algae.
