Dr. Russell Sharp of Eutrema Limited breaks down why algae is a problem in hydroponic and greenhouse reservoirs—how it competes for nutrients and oxygen, clogs lines, and risks crop and food-safety issues. He compares small-scale cleaning methods with the challenges of large-volume systems.

The episode outlines chemical sterilisation options (hydrogen peroxide, peracetic acid, chlorine dioxide), what to avoid (copper, bleach, quats), and non-chemical solutions like ultrasound, UV/ozone and Eutrema’s chitosan flocculant for removing algal biomass.
