This mini natural pool on the roof directly on the Genoa coast was renovated in 2017. The old filter was completely tight due to the wrong choice of material (phosphate-containing lava rock), wrong construction and wrong loading with energy-guzzling pool pumps. In addition, there was no surface suction.
A skimmer was added and a quick-flow filter with lime gravel and a bubbling device, as well as an energy-saving Messner pump, was installed. Now it is again combining clear natural pool water with impressive views of Albaro and the Bay of Genoa.
