Lanthanum Chloride for Algae Control – Case Study

The Problem

A lake owner in Ohio struggles with phosphate reduction and algae control in his 40 acre feet pond. The high levels of phosphates were beyond the acceptable threshold, causing algae blooms in the summertime. In the past, copper sulfate, a known toxic lake treatment chemical, was used as an aquatic herbicide. The lake owner was exploring a more effective and non-toxic chemistry.

The Requirements

• Reducing phosphate concentrations from 0.15 ppm to less than 0.02 ppm.

The Solution and Final Results

After dosing Ecologix’s high purity lanthanum chloride and mixing it well into the lake, the lake owner was able to see a 90% reduction in phosphate levels. In addition, Ecologix’s lanthanum chloride was able to control the algae issue alone. Because copper sulfate usage was avoided, the pond had many more fish eggs and newly hatched fish.
