Application:

To remove ammonia and nitrite (bacterial nitrification) from highly stocked ponds tanks and fish display vats. Surface area: 1 cubic foot of quartz sand media has an available surface area, when fluidised, of 6,200 square feet. (576M2 ) As water cannot track through the media, this means ALL of it filtering.
Capacity:

The biological filtration capacity of any media depends on the available surface area for beneficial bacteria to colonise. The bigger the area = more biological filtration capacity. This doesn't mean that Flocor is as good a biological medium, but you just need more of it!
Operation:
Selected grades of quartz sand are placed in an enclosed reaction vessel, into which pond water is pumped, the velocity of the water lifts the sand and separates each particle, as the water rises up the vessel, gravity causes the sand particles to fall back, As long as the pump is running the sand remains in constant motion, this is the fluidised state which has a very high capacity for the removal of ammonia and nitrite.
Rate of water flow will control the height of the bed once in motion, small pumps will only be able to lift the bed a a short distance whereas a more powerful pump may lift the bed to the top of the filter. In these circumstances the by-pass is used to regulate the flow through the filter.

Our fluidised bed filters can be semi pressurised to allow a constant pumping rate, so water exits the filter at the same rate it enters, this means that it can be located in the filter bay. Also as the water flow through the filter is constant, this gives it a unique self cleaning ability. Fluidised bed filters cannot settle or clarify the water so good settlement using vortex and densely packed brush chambers prior to it are advisable. Filter efficiency is directly related to the amount of oxygen available in the water, so good aeration before the water enters the filter is advisable.
