Shut off the water flow to the Filter.
Lower the water level inside the filter by removing the safety cap and opening
the Drain Valve located at the base of the Filter Body.
A garden hose with a 3/4"connector can be attached to the outlet of the Drain
Valve.
Open the Filter by removing the gray Thread Ring and Filter Lid and remove
the filter material to be cleaned and/or replaced and treat the filter media as
instructed below.
Reassemble the filter making sure to wipe the O-ring with a clean cloth before
replacing the Filter Lid and restart as described above.
Model 375 & 380: unplug the UV Lamp Transformer and shut off the water
flow to the filter.
Open the Filter by removing the gray Thread Ring and Filter Lid (with UV module
attached taking care to lift the lid straight up so as not to damage the Quartz
Sleeve.
Clean the Mechanical Filter Media as described below.
Rinse using a garden hose with a nozzle. To get the best results direct the strong
stream of water between cartridge pleats.
A build up of some organic matter on the outside of the Quartz Sleeve, Middle
Pipe and Base Plate may occur. When cleaning or replacing the filter cartridge
wipe these items with a damp cloth to remove the organic matter.
Reassemble the filter making sure to wipe the O-ring with a clean cloth before
replacing the Filter Lid and restart as described above.
Polystrand Mechanical filter pads - models 317, 318, 319 & 380
The tough Polystrand Filter Pads can be cleaned and reused many times and
will maintain a higher filtration efficiency if they are not allowed to get too
dirty! To clean, rinse each pad in a strong stream of water.
To clean imbedded organics, soak the Filter Pads in a 2 gallon bucket of water
with 2 cups of liquid bleach for 6 to 8 hours before rinsing. It is important
to flush all of the bleach out of the Polystrand filter pads before returning
them to the filter.
Polystrand Bio-filter - models 318 & 340
When conducting regular maintenance on a filter containing a Polystrand Biofilter
place the Bio-filter in a container of tank water to maintain biological
activity. Due to the build up of organics, over time the Polystrand Bio-filter
material may clog. There are a number of layers of Polystrand filter pads
throughout the filter. To improve flow through the filter without destroying
the biological activity clean the filter media in sections, a few layers at a time.
Allow for at least a week between each section, thereby permitting biological
activity to re-establish in the cleaned sections.
Ocean Clear Carbon - models 319, 320 & 325
Should the Ocean Clear Carbon become clogged with particulate matter it may
be washed during regular maintenance to restore better water flow. It is
preferable to use water taken from the aquarium so as to preserve any biological
activity that may be present. The effective life of active carbon varies according
to the conditions of each individual system. As a guide the 20 oz Ocean Clear
Carbon for models 319 and 325 should be replaced approximately every 2 - 3
months. The 7 lb Ocean Clear Carbon for the model 320 should be replaced
approximately every 6 - 9 months.
25 Micron Ocean Clear Pleated Cartridge - models 325, 340 & 375
The 25 Micron Cartridge can be cleaned and reused several times. Before
cleaning, remove any additional filter material present in the center of the
Cartridge.
Clean the dirty Cartridge by soaking it in a 2 gallon bucket with 2 cups of liquid
household bleach for about 8 hours.
Rinse using a garden hose with a nozzle. To get the best results direct the strong
stream of water between cartridge pleats.
