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
