Is beneficial bacteria essential to my pond?


Absolutely!  While many pond owners view using bacteria as an unusual way to purify their water, it is actually the most natural way to do it. That is how nature cleans the environment. Ultimately all waste products in the environment have to be recycled back to the biosphere, and bacteria are nature’s recyclers.

The most important of these cycles from the standpoint of a pond is the nitrogen cycle. Here is a simplified depiction of the cycle.

One of the common by products of protein breakdown, like the protein in fish food, is ammonia. This ammonia can be toxic to fish and other aquatic life in concentrations as low as 1.0 mg/L depending on the Ph. Fish emit this through their gills. The majority of the ammonia in the pond can be traced to this source. Some can also be traced to the breakdown of uneaten fish food and plant material. When a pond is conditioned or capable of cycling, it means that the necessary bacteria have been developed to convert the ammonia to nitrite and, subsequently, nitrate. In many ponds, this nitrate can accumulate and provide nutrients for unwanted plant growth, i.e. algae. A good bacterium like Microbelift PL, Ultra clear SST, or Pond Care Ecofix allows your pond to take the nitrogen cycle another step by further chemically reducing the nitrate to nitrogen gas, which then harmlessly bubbles out of the pond.

Another important natural cycle is the carbon cycle. All living things primarily comprise carbon. Fish waste contains a carbonaceous component. Much of the sludge that builds up on the bottom of most ponds is organic –made up of carbon compounds. Products that contain bacteria and enzymes such as Crystal Clear Biological Clarifier,  Microbelift  Sludge  Away, and Pond Care Pond-Zyme  all do a great job in keeping ponds clean and sludge free.
