The Emperor 400 Filter is created with
advanced system technology that effectively and efficiently provides all three
necessary filtration elements - mechanical, chemical, and most importantly,
biological filtration for both freshwater and saltwater aquariums.
The Heavy Duty Emperor Filter Cartridges provides superior mechanical and
chemical filtration. Mechanical filtration traps solid debris like uneaten food
and fish waste in the dense microfibers. For chemical filtration, each cartridge
is packed with Black Diamond Premium Activated Carbon.
The filter also includes two Refillable Media Containers that can hold an
additional amount of Black Diamond Carbon, White Diamond Ammonia Neutralizing
Crystals or Diamond Blend.
The patented BIO-Wheel is the undisputed best biological filter-the ideal
culture site for the growth and proliferation of beneficial bacteria responsible
for nitrification in aquatic environments. The BIO-Wheel never clogs and never
needs to be replaced.
The Emperor 400 features a revolutionary two pump design. They send water in two
different directions through the filter to provide balanced filtration. The Flow
Pump routes water through the filter cartridge which provides mechanical and
chemical filtration. The BIO-Pump pressurizes and send a stream of prefiltered
water through the spray bar to power-drive the BIO-Wheel. The filter also
features an adjustable Spray Bar Knob that can be turned up or down to change
angle of the spray bar or water flow when feeding.
As the spray-bar driven BIO-Wheel turns, it contacts water and air, providing
the bacteria with oxygen they need to grow. Because it is a wet/dry biological
filter the BIO-Wheel provides bacteria with as much as 30,000 time more oxygen
that any underwater biological filtration. More oxygen means more bacteria
working working hard to keep your tank ammonia-free and sparkling clean.
The filter has a flow rate of 400 gph and is recommended for aquariums up to 80
gallons. It includes two BIO-wheels, two refillable media containers, and two
