Aquaculture installations around the world are often plagued by virus and parasite problems. Treatment can be difficult and often requiring vaccination either by hand or automated methods, both of which are costly exercises.
Disease or parasite outbreaks often result from stress factors which mostly often due to water quality related issues resulting from a range of factors, however, most of these factors start with poor organics removal from the systems. 
Efficient and effective particulate organics removal forms the basis of ensuring all the other components are able to focus on the aspects they are particularly designed to do.
Disease or parasite problems are often exacerbated by anaerobic zones in biofilters, due to high sludge generation 
and poor removal protocols. The excess sludge is as a result of the biofilter acting as an organics filter first and then as a nitrification site. Many viruses and parasites relish the low pH and DO zones of the sludge as a primary breeding site in the system.
Dryden Aqua's philosophy is to treat the problem at source. AFM® is bio-resistant and will not support biological growth. As long as standard backwash protocols are respected, bacteria and pathogens cannot colonise the media and this source of perpetuation of infections is eliminated. The lack of bacteria and biofilm in the filter also ensures that primary protection is afforded, as filtration quality is both better (1 micron) and more stable, while preventing the accumulation of particulates in other areas of the system.
If infected fish are introduced into a system or, if other factors are driving infection rates, then AFM®ng's 1 micron filtration will reduce the parasite load by removing free swimming stages in parasite life cycles, such as the Theront stage of the Cryptocaryon life cycle.
1 micron filtration with AFM® will easily and consistently remove the vast majority of motile or suspended bacteria and parasites in each filtration cycle. As AFM® is bio-resistant, the media will not support the subsequent growth 
and proliferation of sedentary or encysted forms, such as the Tomont stage of Cryptocaryon or Vibrio spp., that would otherwise colonise the filter. Proliferation of bacteria within an AFM® filter is limited by the bacteria's inability to attach to the AFM® grains and by their periodic evacuation in backwash water.
