Algae Control & Barley Products

Algae Control

Algae blooms are a common occurrence in Koi ponds and water gardens. Place a glass of water out in the sun and it will turn green in a matter of days. Green water, commonly known as “pea soup” is most often caused by free floating algae which can flourish in a Koi food full of excess nutrients and plenty of direct direct sunlight. To help prevent algae blooms in your pond, we recommend plenty of shade. Covering your pond approximately 70 percent with shade can help drastically to prevent algae blooms from taking hold.

Many ponds continue to experience green water even after providing shade. This can be due to a variety of factors, including the quality of food used and the limitations of your pond filtration system. For these instances, we offer a large selection of algaecides, barley, and other algae control products. Used correctly, an algaecide and can effectively eliminate green water from your Koi pond, water garden, or any outdoor feature. Care must be taken, however, when using an algaecide.

Algaecides absorb dissolved oxygen in your water. For this reason, it is extremely important to make sure your pond is well aerated when treating with any algae control product. In most cases, simply leaving your waterfall running is sufficient. But for larger ponds with a lot of Koi fish, we highly recommend installing an aeration pump before treating adding any algaecide product to your pond water. This is especially true for ponds with large Koi, as larger fish require considerately higher oxygen levels to survive.

When used as directed, algaecides are safe for use in ornamental ponds, backyard Koi ponds, and water gardens of all sizes. Afforded at an affordable price, algaecides also offer an economical alternative for pond owners when installation of an ultraviolet clarifier is not an option. Also referred to as ultraviolet sterilizers, UVs effectively kill free floating algae in ponds without depleting oxygen levels. For more information about UV sterilizers, please visit our UV Sterilizers / Clarifiers page.

Barley straw is a natural solution to algae control which does not involve the risks of using an algaecide or the expense of purchasing an ultraviolet sterilizer. Completely fish-safe and affordable, natural barley products are extremely popular for use in Koi fish ponds, outdoor water gardens, lakes, and commercial water features. The lone drawback to using natural barley products in a pond is the barley itself tends to break down over time, making it less effective and often creating issues for your pond filter as broken down barley can often filter through your pump and into the filter chamber itself.

If you are experiencing green water in your pond or water garden, you have definitely come to the right place. We offer a wide selection of quality algaecides, natural barley, and algae control products specifically designed for use in outdoor fish ponds.
