FILTER SYSTEM
MEDIA MESH TIE-STRING BAG PRE-FILTER
We recommend a media rinse out in warm water every month, and a replacement of the media itself every 3 months… – Nano
To remove Series-I Box Filter w/ C.O.D. top cover housing, first lift off the foam collection cup lid with its attached foam collection cup float level indicator and foam collection cup float level indicator ball and set them aside.
Next twist and pull-up simultaneously on Series-I Box Filter w/ C.O.D. bioskimmer foam collection cup, this will unseat it from the top neck of the high flow evaporative bioskimmer – foam generator body and allow for the separation of the box top cover or box top enclosure housing from the box bottom enclosure housing.
At this point, the entire box top enclosure cover/housing can either be lifted off completely and set aside, (this same procedure can be used later for servicing the internals of the unit; but for general maintenance at start-up, the box top enclosure cover/housing can be lifted up and clear of its internals and twisted sideways while stationed on the high flow evaporative bioskimmer’s foam generator body to provide ease of access to the overall workings inside the Series-I Box Filter w/ C.O.D. unit without the need to remove it completely.
Next, with the inside of the box bottom enclosure housing accessible, use a slight tug to verify that the high flow bioskimmer/skimbob air injection tubing is secure in place on the small nipple and air-tube venturi connection which is located midway out on the supply nozzle neck of Series-I Box Filter w/ C.O.D. box bottom enclosure dual head system pump with venturi. The unit is supplied with enough bioskimmer/skimbob air injection tubing so that the box top enclosure cvr/housing can remain openly separated from the box bottom enclosure housing without the need to disconnect the bioskimmer/skimbob air injection tubing umbilical which ties the two together.
Visually inspect the media carbon pre-filter and the sponge media pre-filter to see that they are seated down low within the front inflow section of Series-I Box Filter w/ C.O.D. box bottom enclosure cvr/housing and positioned on the bio-tower generator drip tray supply intake pipe (if present) and also that the bio-tower generator drip tray supply pipe is seated securely.
After clarification, verify that bio-tower two phase, three stage, bacteria storage generators are also seated snugly under the bio-tower generator drip tray supply pipe, bio-tower generator drip tray splash guard, the bio-tower generator drip tray pre-filter, the bio-tower generator drip tray (is present).
Next replace the top cover enclosure housing, this will include its water top off, fill/feed port, high flow evaporative bioskimmer foam collection cup lid with its attached high flow bioskimmer foam collection cup float level indicator and high flow bioskimmer foam collection cup float level indicator ball, high flow bioskimmer foam collection cup, the dosing tube, dosing tube seal, dosing tube cap/stand, manual soak feeder attachment, or automatic soak feeder attachment.
As the dual head system pump w/ venturi draws in water, the untreated liquid is drawn in from both the top and bottom of the habitat area’s water column. Firstly, it arrives via the box bottom enclosure housing’s lower box bottom deep pull keyed extension down pipe in-flow slot, where the box bottom deep pull keyed extension down pipe is mounted (if present), and the vac skimbob assembly (if present), and the corresponding deep pull extension down pipe strainer and extension down pipe strainer sponge media pre-filter (if present). (These being bypassed if the box bottom down pipe bypass plug is present, and is used to increases intake water flow at the top surface water skimming slots and Secondly, it arrives via the same sets of top surface water skimming slots.
Referring next to the media sponge pre-filter and the media bag carbon pre-filter where the water is initially screened of detritus and debris before it enters into the pumping system by the down pipe strainer sponge pre-filter and the media bag carbon pre-filter. These processes incorporates both mechanical filtration and chemical filtration as methods for water purification.
