Red Sea Max S-650 Complete, WITH LED, Aquarium System with LED Lights (S-650, Black) The Red Sea MAX approach to the coral reef experience is. In the ocean coral reefs flourish only where specific physical conditions prevail, such as sufficient light, adequate current, stable temperature and water clarity. The Red Sea MAX concept provides a system that creates these conditions allowing you to keep a thriving, healthy reef aquarium in your own home. The Red Sea MAX Concept takes away the worry about retro-fitting equipment, guaranteeing complete compatibility of the coral REEF-SPEC components built in to the aquarium, allowing you to focus on enjoying the fish and corals within your own piece of thriving coral reef. The MAX REEF-SPEC performance criteria is the result of Red Seas years of research into the sustainable growth of all corals, including the most delicate SPS corals, in an artificial reef environment. Keeping the reefs delicate creatures in a closed system requires special attention to water quality, by maintaining parameters within the narrow range that supports life. Effective filtration systems are made up of a number of elements, each performing complimentary tasks. Sufficient water movement is crucial for the well being of static coral reef species and helps maintain proper water quality parameters. Water flow provides the corals with the nutrients and minerals (e.g. calcium) necessary for growth as well as flushing away mucus and preventing stagnant areas where decomposing organic matter would otherwise accumulate.
