Last Year the number of major Blue-Green Algae Lakes increased from 9 to 22 Lakes in Alberta alone.

How many smaller bodies of water are affected by Blue-Green Algae?


Have you experienced a decrease in water quality?

The County of Orange and the City of Dana Point conducted a Pilot Program to test the effectiveness of using six Oloid units to improve the water circulation and the water quality (i.e. reduce indicator bacteria levels) at Baby Beach, Dana Point. The pilot program consisted of measuring and comparing indicator bacteria levels with and without the Oloid devices operating.



Water features at a private golf course in the southwest have chronic algae blooms during the spring and summer months. The high temperatures and high nutrients from the fertilizing process during these months create optimal conditions for algae growth. The lake on these months creates optimal conditions for algae growth. The lake on the 4th Hole has the most severe problem despite having two fountains and several fine bubble aerators on the bottom. A pilot test was conducted in a portion of the lake to determine the OLOID effectiveness at area of the lake, approximately 0.3 acres. Based on visual observations, the algae in the cove have been nearly eliminated after 5 weeks.


Dissolved oxygen (DO) and temperature were measured in the cove to determine the effects of the OLOID unit. DO concentrations were taken at the surface on four occasions and used to generate iso-concentration maps of dissolved oxygen levels in the cove. Measurements were taken weekly between 2 and 5 weeks after installing the OLOID. During this time, the average surface DO increase from 5.2 mg/L to 7.7 mg/L.


Note: Overall percentage improvement of Oxygen Saturation.

The temperature varied between 26 and 19°C. Since dissolved oxygen depends on temperature, which limits the maximum amount of DO in the water; the percent oxygen saturation (summarized in the table below) was calculated for each sampling event based on the average temperature, average DO, and DO saturation at the average temperature. The percent oxygen saturation shows continuous improvement since installation of the OLOID. Above Average temperature (°C) Average Surface DO demonstrates improved Oxygen Saturation.


As you can see that the Oloid 400X is an affordable and effective solution to worsening water quality issues.
