protects filters from damage by preventing the intake of objects, which are too large and also intended to protect fish from being trapped in the filter.
Filter for removing gross contaminate before the product stream enters a filter separator. Used to remove gross solids.
This is a small mechanical filter attached to the input to another filter, usually biological. It is there to make sure that the biofilter does not get clogged with gunk, decreasing its effectiveness. edox Redox, or reduction-oxidation potential, is a measure of how easy it is for organic reactions to take place. This is an indicator of water quality, measured in millivolts with a special probe. Higher values are better. Redox controllers use an ozone reactor to raise the redox potential.
This is a small mechanical filter attached to the input of another filter. Usually a sponge.
A prefilter is used mainly in marine tanks to remove large particles as the water leaves the tank, enroute to the sump.
This is a small mechanical filter attached to the input to another filter, usually biological. It is placed there to make sure that the biofilter does not get clogged with gunk, decreasing its effectiveness. In this manner it acts to remove large particles from the water, such as leaves, uneaten food, fish waster, etc.
an absolute necessity or it won't be filtering for long
an internal box (strategically placed inside the aquarium) that skims water from the surface of the tank to initiate the filtration process
Filter that provides first stage air filtration to remove larger particulates and prolong the efficient use of a HEPA filter.
A filter unit installed to protect a second filter from high dust concentration or other environmental conditions. The prefilter usually has a lower efficiency than the filter it protects.
A type of filter defined in an adapter configuration file for filtering raw events at the source, before any adapter processing.
A simple mechanical filter, designed to remove large particles as the water leaves the tank. It's intended to be easily accessable and frequently changed, thereby reducing the nutrient load feeding the nitrification cycle. Seemingly more useful in marine aquariums than freshwater set-ups.
A filter used in many air purifiers that is designed to capture particles 1 micron in size and larger. Some air purifiers used activated carbon as their prefilter to remove odors and gases. A prefilter will extend the life of a HEPA filter.
Filter for removing gross contamination before the liquid enters the main separator/filter.
