The biOrb HALO 30 has two versions of LED lighting. A standard version has a biOrb LED light above the bubble tube. The halo version is fitted inside the lid as a ring of LED lights to give the contents of the aquarium a real 3D appearance. At night the halo version automatically switches to the calm moonlight setting. A light sensor allows you to set the exact lighting conditions for the automatic switching to moonlight. Controls that are a joy to use The lid closes reassuringly with a magnetic catch and the airline is subtly hidden away in one of the feet at the back of the tank. biOrb HALO uses the same proven filter as the rest of the biOrb range. To maintain your biOrb HALO 30 all you do is simply replace the filter cartridge every four weeks and change a third of the water. For safety and peace of mind, the lights and pump are low voltage and are backed by a 12 month guarantee. The aquarium itself is made from acrylic, which is ten times stronger than glass. You can enjoy all the technology of an advanced aquarium set up, supplied in one box. The biOrb HALO 30 is the perfect aquarium for anyone new to fish keeping.
