PRESSURIZED FILTER SYSTEM
INSTALLATION AND OPERATING INSTRUCTIONS
HOW FILTRATION WORKS:
Both biological and mechanical filtration are essential for every pond; without them, your fish would be
harmed by ammonia generated by the accumulated fish waste. The beneficial bacteria bed that builds on the
filter media nitrifies any ammonia in the pond making it a healthier environment for aquatic life. Mechanical
filtration removes debris in suspension in pond water keeping it cleaner and clearer.
Biomechanical filtration depends on the establishment of a colony of bacteria on the surface of the media that
converts dissolved toxic nitrogenous waste to harmless compounds. When the bacteria are given the proper
environment, they grow in a thin biofilm on the surface of each piece of media. The larger the surface area of
the media, the larger the bacterial colony.
The media must first establish itself to handle the load of dissolved ammonia. Depending on the water
temperature, it can take 2 - 4 weeks for the filter to establish itself in the pond environment. The ultraviolet
filtration should be left off during initial seeding to allow the bacteria colonies to grow.The time required
varies depending on climate, weather conditions, fish load and feed rates. Until the colonies grow large
enough, the pond owner must take care to monitor levels of ammonia and nitrates in the water and take
appropriate measures to correct any dangerously high levels.
The ultraviolet clarifier/sterilizer (UV) produces a wavelength of light that inhibits algae from reproducing by
damaging its DNA. Please note that UV light does not kill algae that cling to the sides of ponds. If your pond
has string algae you can add Pondmaster Pond Fix with activated barley to inhibit growth of floating Algae
and Pondmaster Oxy Scrub to remove algae from rock surfaces.
BEFORE YOU BEGIN:
• READ ALL CAUTIONS - - Ponds, outdoor electricity and UV lamps can be extremely hazardous if misused.
• CHOOSE LOCATION for your POND FILTER ARRANGEMENT - - There are several options setting up a pond filter.
• SELECT THE PROPER SIZE PUMP - - The right pump will ensure safe, quality filtration.The wrong pump will
lead to inferior filtration and possibly damage the filter.
• DECIDE ON OPTIONAL ACCESSORIES - - It is easier to install accessories BEFORE installing the filter system.
• COLLECT ALL THE ITEMS NEEDED TO COMPLETE THE PROJECT - - Avoid 20 trips to the hardware store!
• READ and KEEP ALL INSTRUCTIONS - - Know how to use and maintain your filter.
• ***FOR UV MODELS*** PREPARE POWER REQUIREMENTS - - Prepare all electrical with care. Read and follow all instructions.

NOTE: This filter is intended to pull suspended solids out of the
water column. It is NOT designed to remove leaves and large
solids from the pond. It should not be used as a pond vacuum.
All pumps used with this filter must be used inside a Pump Bag
or with a Skimmer or prefilter to prevent large debris from enter-
ing the filter chamber and blocking the biological filtration.
