Algae Control & Prevention

What is Algae anyway?

Alga (yes, alga) is one of the most common problems faced while maintaining a pond, lake, or water feature. It forms a big and diverse group of eukaryotic organisms that love sunlight, warmth, and high-nutrient bodies of water like your pond.  Like plants, algae uses photosynthesis to convert light into energy. It doesn't have a root system like traditional plants and often grows floating on the waters surface, across submerged surfaces, or in the water column.  In abundance, algae will mat on the surface or spread throughout the water column shading your pond, preventing plant growth & reducing oxygen content.  If left unchecked it can deplete your pond of oxygen killing fish and other organisms.

Algae without Algae Control

Algae does have its benefits though. When it comes to your pond or lake's ecosystem it can be a food source for small fish (like fry) and insects or even a home for micro-organisms.  However, its drawbacks often outweigh its positive aspects.  It is unsightly; covering or clouding up the water preventing a clear view throughout the pond (and don't get us started about the smell).

Aquatic Plants for Algae Control

Aquatic plants play a massive role in algae reduction in ponds and lakes by filtering water and consuming the high nutrient content that the organisms also love to eat.  We encourage pond owners to include a variety of submerged aquatic plants and marginal pond plants to naturally assist in mitigating algae problems.

Preventative Water Treatments

Water treatments are a fast quick solution but also temporary unless used in conjuction with other algae reducing methods such as other treatments, water filtering, and pond plants. Water treatments should be used carefully and as directed.

Barley Treatments 

Barley extract and bales are used as natural inhibitors to algae growth in your pond and water feature. Using barley in conjuction with other treatments and solid pond maintenance practices will help keep harmful levels of algae at bay.

Biological Filtration

Biological filter media is a necessity in any aquatic system that aims to reduce algae and/or clean water of debris and toxins. Filter media adds large amounts of surface area for beneficial bacteria to colonize while also catching larger particles preventing their return into your water.
