Is a natural swimming pool difficult to maintain ?

No, during the first year, the narrow supervising and maintenance are essential. Once the biological balance of the swimming pool is reached, we probably need professional care. Swimming pools need weeding and to be cleaned with vacuum cleaner. If swimming pool is surrounded by trees, dead sheets will be withdrawn. Plants will be cleaned.

Generally, maintenance is much less than for a conventional swimming pool. Ducks and fish are not authorized for hygiene reasons.
