Fish Mate. Gravity UV & Pond Filter Combo Units
Fish Mate range of UV plus Bio pond filters combine UV clarification and biological filtration to give a total purified water pond. All Fish Mate Gravity filter models consists UV tubes, quartz tube replacement, thus eliminating issues of scaling and frost damage with conventional UV clarifiers. UV plus Bio filter is suitable for ponds up to 30000 litres. See the table below to make the ideal selection.
These filters work by killing algae by exposing the algae that cause 'green
water' to UV (ultra violet) light. The
algae
clump together and reach a size that the filter's mechanical section can remove
them (normal single algae are far too small to be removed in any pond filter).
The mechanical filter section contains profiled filter sponge pads which trap
algae clumps and other large particles. These sponge pads are easily rinsed.
After mechanical filtration is finished the biological section of the combo unit
takes over. This unit contains Alfagrog (called Supra in USA) which is a
powerful biological filter medium (also called biomedia). Supra has more than
100 times the biological surface area of most types of plastic media and this
allows much larger colonies of bacteria to be grown. In tuen large bacteria
colonies remove ammonia and nitrite more quickly and efficiently.
General Pond Filter Descriptions
Compact UV and Bio Pond Filter (see table below) ... designed for small to medium ponds, this easy to hide filter guarantees crystal clear water. Inlet Size - 3/4" , Outlet size - 1-1/4". 7" H x 14-1/4" W x 9-1/2" D. 8 watt UVC (ultra violet light clarifier to kill algae) for ponds up to 1,000 gallons, 300 gph pump is about right for this unit. Use 16 watt UVC for ponds up to 2,000 gallons

What Gravity UV plus Bio pond filter does!
-
Algae destruction. Passing the single celled algae that causes green water in front of UV-C light.
-
Mechanical Filtration. Profiled filter sponge pads will trap algae clumps algae partcles.
-
Biological Purification. After mechanical filtration, the pond water passes through SUPRA biological filter media. SUPRA enables rapid growth of aerobic bacteria resulting to removal of lethal ammonia and nitrite
