-==== Biofilm ====
-Biofilms are a complex community of microorganisms that adhere to surfaces and form a protective layer. They are commonly found in aquatic environments, including iAVS systems. Biofilms are important in iAVS systems because they play a key role in water filtration and nutrient cycling.
-In iAVS systems, biofilms form on the surface of the sand bed and help to remove excess nutrients from the water. The biofilm is made up of a diverse community of microorganisms, including bacteria, fungi, and algae. These microorganisms work together to break down organic matter and convert it into forms that can be used by plants and other aquatic organisms.
-Sand is an important component of the biofilm in iAVS systems because it provides a stable and porous substrate for bacterial growth. The sand bed acts as a biofilter, removing excess nutrients from the water and providing a habitat for beneficial bacteria. These bacteria then form a biofilm on the surface of the sand bed, which helps to improve water quality and nutrient cycling. Biofilms are also important in iAVS systems because they help to prevent the buildup of harmful compounds in the water, such as ammonia and nitrite. By removing excess nutrients from the water, biofilms help to create a healthy and stable environment for both the plants and the fish in the system.
