Filter Preparation
3) Place a piece of duct tape over the riser tube of one of the tanks, so no gravel or carbon
or bone char enters the riser while filling. Both tanks are the same and it does not matter
which tank is used for the carbon and which tank is used for the bone char. Gravel will be
poured in the tankS FIRST.
4) Use the Blue Funnel provided, to pour the gravel and carbon into one tank and gravel
and bone char in the other tank. Pour it evenly around the hole to ensure it is well distribut-
ed in the tank and pour slow enough, to keep from plugging the hole. The gravel should be
poured in the tank first, then pour the carbon or bone char in the tank second. Pour all the
gravel, carbon and bone char that was shipped in the tanks. A helper may be needed to
hold the funnel during the filling process. It is recommended that a dust mask and safety
goggles be worn to prevent possible injury.
5) Once the carbon and bone char tanks have been loaded with gravel, carbon and bone
char, remove the duct tape and funnel and fill the tank with water (if possible/practical) and
let it soak. This will decrease the rinse time needed to remove the fines/dust from the me-
dias during startup. If this cannot be done, the rinse time may take longer but it does not
affect the performance or operation. Usually 1-2 hours of soak time is sufficient to reduce
the rinse time during startup.
