Where is the ponds filtration system?
Ans: There aren’t any. You need not be bothered with cleaning or changing filters; no spare parts to buy or stock up. Maintenance is carried out simply by partial removal of pond water for watering plants, and replacing with clean tap water. The pond water is thus recycled. And as more submerged plants are introduced, they will provide the pond with oxygen. The fountain itself helps in aeration too.
