Stage 1:
Algae Destruction. By slowly passing the single celled algae that cause 'green water' in front of U.V.-C light, the algae is caused to clump together and start to die.
Stage 2:
Mechanical Filtration. Specially developed, profiled filter sponge pads will trap algae clumps plus other large particles and are easily rinsed for regular maintenance.
Stage 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.
