Strictly speaking, microbes can be bacteria, plants or animals; but we usually use the words bacteria and microbes interchangeably. Microbes – in the form of biofilm – are the biggest factor in removing nutrients from water. Microbes occur naturally in waterways, and they can also be bought commercially. Our research indicates that naturally-occurring microbes are as effective as commercial microbes at removing nutrients. Microbial activity is what makes an aquatic system work. Microbes work really well on floating islands, even without plants – as evidenced by our research studies.
