NANOREEF DUO is a modern, fully equipped aquarium set designed for creating a small marine aquarium. The specialised LEDDY SLIM DUO MARINE & ACTINIC lamp emits light that is ideal for corals and other sea animals. A high-capacity hang-on filter purifies the water and keeps it in motion. The NANOREEF DUO set is an excellent choice for keeping corals, shrimp, small echinoderms, nano reef fish, and small marine fish. Its maintenance is very easy and does not require much effort. Apart from regular cleaning, you should change 10 litres of water every week.
