Good for ponds up to a 1,000 gallons in full shade, lightly stocked.Filtration stages:Stage 1: Algae Destruction - by slowly passing the single celled algae that cause 'green water' in front of UVC light, the algae is caused to clump together and start to die.State 2: Mechanical filtration - specially developed, profiled filter sponge pads will trap algae clumps plus other large particles and are easily rinsed for regular maintenance.State 3: Biological Purification - after mechanical filtration, the pond water passes through Fish Mate SUPRA Biological Filter Medium, possessing over 100 times the biological surface area of conventional plastic media. The specific structure of SUPRA enables rapid growth of aerobic bacteria resulting in removal of lethal ammonia and nitrite.Size:9.5" diameter x 11" high.  (less)

of filtration, the water enters a chamber with a coarse filter brush that strains out debris, settling it into the chamber for easy removal. The second stage incorporates a specially developed, profiled filter sponge that traps most remaing particales. The final stage contains supra biological filter media for the removal of ammonia. Maximum pond volume recomended for this filter is 1000 gallons. Under extreme conditions such as high fish stocks or Koi, low plant stocks, and sunny or hot locations a 500 gallon pond volume is recomended. A pump that is no more then 500 gph is recommended. The filter is easy to maintain and is designed to blend in with natural surroundings. Inlet and Outlet:34" inlet and (2) 1 14" outletsSize:14" L x 9 12" W x 5" H  (less)
