What is biological pond?

First let’s find out together what is an ecological or a biological pond if you wish. A biological pond is similar to a regular decorative pond; the difference is the filtering system. This means to install a natural filtering system using substrates, plants and fish that clean and filter the water.Click to see full answer. Also question is, what is a biological filter?Biological filtration is the action of bacteria in the tank breaking down dangerous ammonia, converting them to nitrites, and then the nitrites to the less toxic nitrates. The process of biological filtration, also known as the nitrogen cycle, involves the movement of harmful wastes through the filter.Additionally, can fish survive in a pond without a filter? It is possible, but a fish pond needs oxygen for the fish to survive. As oxygen levels are so vital to the wellbeing of your fish, a bubble stone or waterfall will also help to bring oxygen to your pond. It is possible to keep a fish pond without a filter, with regular doses of Aquaplancton. Beside this, how does a biofilter work? When applied to air filtration and purification, biofilters use microorganisms to remove air pollution. The air flows through a packed bed and the pollutant transfers into a thin biofilm on the surface of the packing material.How do I make my pond filter bigger? Steps Get a bucket or trash can with a sealable lid. Purchase a water pump if you don’t already have one. Lay out where the pump and filter will be located in relation to the pond. Buy rubber hose to connect the filter to the water pump. Cut a hole in the lid of the container that’s just large enough for the hose.
