Combined U.V. and Biological Filtration for crystal clear, purified water
Flip up lid for easy maintenance
' Frostproof ' quartzless U.V. chamber
Includes SUPRA BIO MEDIA
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 perish
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 biological filter medium, possessing over 100 times the biological surface area of conventional plastic media enables rapid growth of aerobic bacteria resulting in removal of lethal ammonia and nitrate
