Is aeration necessary?
A number of bacterial strains in Alken Clear-Flo utilize dissolved oxygen in their digestive process. Aeration will enhance the effectiveness of these aerobic bacteria, particularly in aquatic environments. If the dissolved oxygen level of a water body is already very low and Alken Clear-Flo is added, which consumes additional oxygen, a situation may be created in which there is inadequate oxygen for the fish – causing a fish kill! The Clear-Flo bacteria are facultative anaerobes, so they can also work in anaerobic environments where nitrate is available, as an oxygen source.
