Vacuum but twice a year and tend to the plants as needed. The plants will need to be cut back in the fall so they do not die in the bio pool.

The regeneration zone can be along the perimeter of a bio pool or a pond unto itself but connected to the swimming area.

For a true bio pool with no help from ultraviolet light or other such technology, the requirement is half swimming area, half regeneration area.

Natural predators such as water striders and dragonflies will come to live in the enrichment area and feast on mosquitoes. If you chose to have a skimmer installed this will keep mosquitoes in check as well.

A first year bio pool will need at least 60 days to self-adjust, but installing an ultraviolet sterilizer in the pump area will have you swimming almost immediately.

A hybrid bio pool usually has two circulation pumps. One where water is circulated through the plant and rock filters before being discharged back to the bottom of the pond. The second surface circulation system pulls water through one or two skimmers filtering out floating debris. Water drawn through the skimmers passes through some type of filter system, such as a UV filter and/or a biofilter—essentially a box filled with bacteria-laden bio-media—before returning to the pool. A waterfall helps with oxygenation.
